Stack Overflow during Unmarshal

Hi,
I'm using JWSDP 1.6 which includes JAXB RI 1.0.5. I compiled a schema that includes the following section:
 <xs:element name="UNITSTATUS">
 <xs:annotation>
 <xs:documentation>Unit Status Aggregate</xs:documentation>
 </xs:annotation>
 <xs:complexType>
 <xs:sequence minOccurs="0" maxOccurs="unbounded">
 <xs:element ref="UNITVERSION" minOccurs="0"/>
 <xs:element ref="BATTERYSTATUS" minOccurs="0"/>
 <xs:element ref="UNITFAULT" minOccurs="0" maxOccurs="unbounded"/>
 </xs:sequence>
 </xs:complexType>
 </xs:element>The schema compiled without any issues. However, when I try to unmarshall an XML file that includes UNITSTATUS elements in the content, I get a java.lang.StackOverflowError. If I change the xs:sequence element's maxOccurs to 1 and recompile, it works fine (as long as the XML file only includes 1 UNITSTATUS element). Also, if the XML file doesn't include any UNITSTATUS elements, it also works fine. The problem also occurs if I change the xs:sequence element's maxOccurs to anything greater than 1.
Does anyone have any idea what might be causing this or how I could get around it?
Thanks,
Matt

Stack overflow exception when selecting the Organization tab on a contact card

I have encountered a reproducible crash in the Lync 2013 client. The crash happens after selecting the "Organization" tab when viewing a contact card.
The crash appears to happen because of a stack overflow with MSO.DLL. I have applied the latest hotfix for that module but the crash persists.
Before I open a case with MSFT, can anyone offer any insight? Perhaps this is being seen elsewhere?

I actually think I may have figured this out. I took a network trace during the crash. What I found is that Lync is performing repeated LDAP searches over and over until it crashes from the stack overflow. Digging into
the searches, I found the same two user CN's being alternated one after another.
It appears that this crash may be the result of a "Circular Reference" where the two users are each listed as the others manager in their user object.
Example:
User1: Manager = User2
User2: Manager = User1
Proving this as the cause will take me some additional time as these two users are at the top of the Org Chart. :)
I'll update this post with the results when I get them.

C++ stack overflow on desctruction of Set::View

Hi,
I've encountered a problem when querying large sets of data from coherence.
Gven the following code;
 // load cache with a large data set
 char buff[128] = {0};
 for( int i = 0; i < 100000; ++i )
 sprintf_s(buff,128,"key%05d",i);
 // random binary data
 int len = 128 + rand() % 512;
 Array<octet_t>::Handle hab = Array<octet_t>::create(len);
 hCache->put(String::create(buff),hab);
 // query the cache, and print the results
 struct tmpIt
 Filter::View vAll;
 Set::View vSetResult;
 tmpIt *t = new tmpIt;
 t->vAll = AlwaysFilter::create();
 t->vSetResult = hCache->entrySet(t->vAll);
 // iterate over the results
 int ncount = 0;
 for (Iterator::Handle hIter = t->vSetResult->iterator(); hIter->hasNext(); )
 Map::Entry::View vEntry = cast<Map::Entry::View>(hIter->next());
 String::View vKey = cast<String::View>(vEntry->getKey());
 Object::View vValue = vEntry->getValue();
 Array<octet_t>::Handle dt = cast<Array<octet_t>::Handle>(vEntry->getValue());
 ncount++;
 if( (ncount % 2000) == 0 )
 std::cout << ncount << std::endl;
 // delete the struct, thus forcing the destruction of vSetResult
 delete t;On deleting the struct 't' causes a stack overflow deep within coherence. I'm guessing there's some kind of recursive delete that works on smaller data sets.
Can you please advise me on what to do in this situation, as this has put a halt to my coherence integrartion :)
Cheers
Rich

Hi Rich,
I've tried your test out in a few environments using both debug and release builds and have not been able to reproduce the issue. My guess is that it may have something to do with your build settings. Can you try building it using the build.cmd script which we ship with the product. This can be done by creating a new subdirectory under examples for your test, for instance "overflow", place you source code in that directory and then from the examples directory run "build overflow". You can then run the test by executing "run overflow". This is how I've tested an all seems to be ok. Assuming this resolves the issues on your side, you can have a look at the compiler/linker settings used in the build.cmd script and try applying them to your build process. If this does not resolve the issue, it would be useful if you could send us a fully buildable example (and build script) which reproduces it. Also if you could include the OS and compiler versions that would help.
In testing your source code I ran into a few small things I thought I should point out to you.
- while loading if you batch your puts into a local HashMap and then do periodic hCache->putAll() operations loading will be faster:
 // load cache with a large data set
 char buff[128] = {0};
 Map::Handle hMapBatch = HashMap::create();
 for( int i = 0, c = atoi(argv[2]); i < c; ++i )
 sprintf(buff,"key%05d",i);
 // random binary data
 int len = 128 + rand() % 512;
 Array<octet_t>::Handle hab = Array<octet_t>::create(len);
 hMapBatch->put(String::create(buff),hab);
 if ((i % 2000) == 0)
 hCache->putAll(hMapBatch);
 hMapBatch->clear();
 std::cout << "loaded " <putAll(hMapBatch);
 hMapBatch->clear(); - During iteration you should not cast the values back to Handles, but rather only to Views. It is not guaranteed that the cache will return non-const references to the data.
I did validate that the test did not fail prior to making the above modifications.
thanks,
mark

Error #1023: Stack overflow occurred. null

I am entering data inside a datagrid and I have an update button which sends data to a web service. But when I click the update button, I get this error: Error #1023: Stack overflow occurred. null. I filled in the info using SOAPUI and sent it to the web service and it works fine. So this error is inside flex. Would you help me understand what I am doing wrong.
Here is my code:
 protected function updateBtn_clickHandler(event:MouseEvent):void
 if (currentState == "EmployeeNonAvails")
 setNonAvailResult.token = personnelBean.setNonAvail(nonAvailDto);
 else if (currentState == "EmployeeDetail")
 userDto.firstName = firstNameTextInput.text;
 userDto.lastName = lastNameTextInput.text;
 userDto.loginName = loginNameTextInput.text;
 userDto.password = passwordTextInput.text;
 setUserResult.token = personnelBean.setUser(userDto);
 <fx:Declarations>
 <personnelbean:PersonnelBean id="personnelBean" fault="Alert.show(event.fault.faultString + '\n' + event.fault.faultDetail)" showBusyCursor="true"/>
 <valueObjects:UserDto id="userDto"/>
 <valueObjects:NonAvailDto id="nonAvailDto"/>
 <valueObjects:ReasonDto id="reasonDto"/>

 </fx:Declarations>
 <s:Button id="updateBtn" includeIn="EmployeeNonAvails,EmployeeDetail" x="80" y="192" label="Update" click="updateBtn_clickHandler(event)"/>
 <mx:DataGrid id="nonAvailDg" width="875" height="248" editable="true" x="0" y="244"
 dataProvider="{userDto.nonAvails}" includeIn="EmployeeNonAvails">

PersonnelBean is a reference generated by Flash Builder to a web Service. As stated in my original message. I have already tested the web service and it is working fine. I used SOAPUI to send the data via XML and it worked perfectly fine. Besides, when I watch the server log, nothing happens and so Flex is not even sending out the message. Flex is talking to the server because it connects and loads data fine. It seems to fail when I want to send data to the server. But it is failing before it actually sends the data. And it fails during generated code. This tells me there is a bug in Flash Builder. If you look at the generated code for Personnel Bean this is what you see.

What causes a stack overflow with this code?

secIClip.clearStage(secIClip);

var gameClip:MovieClip = MovieClip(root).page_3.gameMC;
gameClip.clearStage(gameClip);

closeClip.clearStage(closeClip);
else{
trace("confused at stop av function");
//showChildren(stage, 0);

It appears that one of the clearStage functions which exists in a loaded swf had an error. I was able to track it down and now it works.

Stack overflow error while creating connection using Oracle10G dirver

Hi,
Our web application built on Servlets runs on the iPlanet web server (In solaris machine). Earlier we used JDK 1.5 update 6 with oracle 9i driver and now got migrated to JDK 1.5 update 10 with same driver. Everything went fine until we started testing the environment with oracle 10G driver. Java 1.5 update 10 with oracle 10G driver throws "Stack overflow error".
Driver version is - 10.2.0.2.0
This occurs only when I access the portal. When I created the single main program and try to run it in the solaris machine it works fine. But wen I try to access the portal keeping this driver under classpath, it fails. Please let me know if anyone have any clues.
When I looked into it, I am able to find that the "stack overflow error" occurs at the point the code line DriverManager.Getconnection("url", "username", "pwd") executes.
Thanks in advance
below the stacktrace of the exception from webserver error log..

Yes, request goes through connection pool but weird
thing is application throws stack excatly where
DriverManager.getConnection gets executed.
Not weird at all.
This is what I am guessing that you did. You changed the driver and some other stuff, like configuration information.
Then when it blew up you tracked down in your code where you see the stack overflow. That happens to be on the connection line. That is not where the overflow 'occurs' - it merely represents where you saw it.
That line however isn't using the oracle driver. What it is using is a connection pool of some sort. That connection pool is configured somewhere. And that configuration is self-referential (or maybe refers to a another driver which refers back to the original.)
And that causes you stack over flow.

Overflow during the arithmetical operation (type P) in program "SAPLHRPT

Hi,
I am currently facing an issue in payroll posting to accounting in international payroll.A run time error "Overflow during the arithmetical operation (type P) in program "SAPLHRPT" occurs. By reducing the amounts on the balance sheet side payroll posting document is created.

Hi Asad,
Does you guys enhancemented this program? I think if it`s standard code, it should give you a error message inform you "amount is too large" or something.
So double click this dump log, to check whether it is a custom code, if yes, to add "TRY CATCH" and give out a message.

Archer

Overflow during the arithmetical operation (type P) in program "SAPLV61A

hi,
    I am getting this error in VA01(sales order)
Runtime error              Compute_bcd_overflow
Except                       Cx_sy_arithmetic_overflow.
Overflow during the arithmetical operation (type P) in program "SAPLV61A
Error in particular line is.
1388           ADD xkomv-kwert TO komp-mwsbp.
Please give me the solution with detail decsription.How to solve with step by step.

Hi,
Instead of directly assigning the value to xkomv-kbetr. Store the value in a temporary variable of type p length 13 decimals 2 . Multiply by 10^n to get the correct result.
Then assign the temp value to xkomv-kbetr.
Sample Code
DATA : lv_temp TYPE P length 13 decimals 2.
lv_temp = ( xkwert * 10^n ) / komp-mgame.
Then assign lv_temp to xkomv-kbetr.
To get proper value, you have to multiply or divide by 10^n .

Error while executing web part: System.StackOverflowException: Operation caused a stack overflow

Hello All,
I have a list with about 70 or so columns. When I try to access a NewForm for this list, I get an 'Unable to display this web part' error.
Looking at the Correlation always says it is a:
"Error while executing web part: System.StackOverflowException: Operation caused a stack overflow."
I have read many pages on the internet that it is due to an XsltTransformTimeOut value set to 1. I have applied the Feb 2012 CU and tried changing the value to 5, 10, 150, 250 and each time I reset IIS before I tried loading the form again. Each one has
failed and the correlation says the same thing (stack overflow).
I do not know what to do next because every page on the net says it is from that timeout value but I have followed the steps properly to change it but nothing has worked.
Thank you for your help!

You may be exceeding the number of columns threshold with 70 or so columns in your list.
Take a look at the Column limits here:
http://technet.microsoft.com/en-us/library/cc262787.aspx#Column
Okay, so please help me to understand this. It says the maximum value for single line of text is 276 and the size per column is 28 bytes. How would I know if I have pushed the limit? I just multiplied 28 x the number of single line of text columns in that
list and the answer is 840. I do have many other columns, such as multiple lines of text and choice. I do not know if the theory above is correct though, because 28 does not go evenly into 276 (276/28 = 9.857)
Please help me understand how to calculate my fields to see if I have went beyond the limits.
Thank you!

Stack overflow user profile doesn't display correctly

The page of Stack overflow user profile is wrongly displayed, blank space on top of page and some info is hidden.

I see what you mean. It appears that the drop-down which says "Summary" is pushing that block of content off to the right (sometimes you can see a sliver of it at the right edge of the page). That problem doesn't occur in the stock Android (2.3.4) browser.
If I use a Fennec useragent string in the User Agent Switcher extension, I can replicate the problem on a desktop browser (''Firefox 13 beta 4''). The drop-down is floated within a container that uses 100% of the width of the screen. The next element floats up alongside the <select> rather than dropping down beneath it because that next element doesn't have a specified width or minimum width.
StackOverflow can solve this problem by editing its CSS to include a clearing rule:
 .inner-wrap {
padding: 5px;
overflow: auto;
'''clear: left;'''
However, as end users, I don't know whether there is anything we can do.
This problem has appeared in sites for years, and it seems unlikely that Firefox will change the way it handles floats to work around developers who forget to clear them. (Guessing as to what the developer must have wanted was something that IE did for years, but I think even Microsoft is starting to require developers to pay closer attention.)

Stack Overflow Exception in EJB Explorer

Hello everyone!
I have correct working EJB which returns in one method and JPA Entity that have bidirectional relationship with other entity. This relationship is @OneToMany and @ManyToOne on other side and all of the related objects are loaded before the end of the method. This EJB is working correctly when used with other components.
I have problems testing this method in EJB Explorer utility that is part of the SAP NetWeaver Aplication Server Java. When i start this method it never finishes and later gets an stack overflow error. Trace is here:
java.lang.RuntimeException: java.lang.StackOverflowError : null
at java.lang.Class.getMethod0(Class.java:2670)
at java.lang.Class.getMethod(Class.java:1603)

at com.sap.ejbexplorer.business.invocation.impl.Structure.fillNestedStructureWith(Structure.java:287)
at com.sap.ejbexplorer.business.invocation.impl.Structure.fillWith(Structure.java:234)
Looks like EJB Explorer is trying to expand all returned objects. Then he gets into the unfinished loop because of the bidirectional relationship.
We are using SAP NetWeaver 7.20 SP04.
Is this error fixed in new version?
Is there some configuration that fix this?
Thank you for any response.

Hi,
is it just for the presence of the JUnit extension, or do you use this class in your Unit testing ?

Element substitution not working properly during unmarshal

Hi everybody,
I've following situation. I have a project (call it project A) which contains a schema (lets call it the abstract schema). In the abstract schema there is an element which was declared as abstract. Furthermore there is another element (call it container) which shall be able to contain as much "abstract" elements as the user wants to. It obvious that an element could not be abstract, so I've created another project (call it project b) which has a schema (call it concrete schema) whichs imports the abstract schema. In the concrete schema I will have some elements which substitute the abstract element from the abstract schema.
Now I've an xml document whichs root element is the container (from the abstract schema), and it should contain the non-abstract elements from the concrete schema. So far so good, everything will be validated, there are no errors. But unfortunately the unmarshal progress will not return the expected result. Validation during unmarshal progress is ok as I said but after unmarshalling the xml file, there is no concrete element in the returned result.
I don't know what could be wrong. Did somebody already worked with element substituion in that way and is able to help me?
Because its very complicated to describe I've created a minimal testcase (http://www.mailing-list-disaster.com/generic-jobengine.tar.gz) . Just compile both projects and run the using-abstract-engine application.
Thx for suggestions and with best regards

Hi Ram
Thanks for the reply.
No it does not take from any other LOV and there is no existing LOV mapping for this item.
Its in the iExpense>Create expense report>General Information screen> Approver LOV
The APPROVER LOV needs to be mapped with the field "Cost Center" which is not there in the standard functionality.

Stack overflow error

Hi..
I have problem with this code.
   class test
       test tt=new test();   //1
       String name1;
    test() {}
    test(String i)
          name1=i;
         //tt=new test();    //2
   public static void main(String arg[]){
              test t1=new test("kj"); //3
} When I use line 2 (nstead of line 1 ) for initializing the ref variable iam not having any problem.
But if i use as in line 1 iam getting stack overflow error..
I thought tht calling a constructor recursivley results in a stack overflow error..
But iam instantiating t1 with a one arg constructor (line 3) for which tt (line 1)is intialized,then where is the recursion happening..
can any one pls clear..
Thnx.
mysha..

please use [code][/code] tags around your code - makes it much easier to read.
I think you have it - consider this code:public class StackOverflower {
    private StackOverflower so = new StackOverflower();
    public static void main(String[] args) {
        StackOverflower mySO = new StackOverflower();
}Running this will overflow the stack since creation of an instance of StackOverflower requires creation of an instance of StackOverflower. This code though:public class NonStackOverflower {
    private NonStackOverflower nso = null;
    public NonStackOverflower() {
    public NonStackOverflower(String s) {
        this.nso = new NonStackOverflower();
    public static void main(String[] args) {
        NonStackOverflower myNSO = new NonStackOverflower();
}Won't, since the creation of a new NonStackOverflower is not required to create a new NonStackOverflower instance.
Did that make sense? I may have gotten confused and failed to illustrate your situation with my code...
Good Luck

"Stack overflow" & "out of memory"

Hello,
I have an issue with javascript code : with my own navigation, which includes additional javascript, I have either a "out of memory" error on the declaration of "var strUrl = http://..." in the CommonOpener_CreateExtObject method, or a "stack overflow" error on the onload="document.PCC.RaiseWindowEvent(event);" event handling in the <body> tag.
When I save the page as HTML and remove the onload event, no error happens anymore.
I think I could remove the onload event generation by modifying the C# code, but it would certainly disable some other feature (I think this event is managing PEI calls or something else).
Any idea on how to fix this ?
P.S : I'm on a .NET platform, I'm going to try to recompile my nav on a java platform to see if it works...

Sebastien,
- Are you using 5.0.1 or 5.0.2?
- Are you by any chance trying to extend the Isomorphic navigation (under 5.0.2, it's called "legacy")?
I would carefully review the pluggable nav you're using and double-check you're including all the necessary javascript in the JavaScriptIncludes() method to make sure you're basically adding everything properly.
The isomorphic nav was particularly hard to extend because it required you add a special DHTML element to close off the menus being inserted. If you base your work off of our new jsportalmenus nav, it's much easier to work with and more reliable: it injects javascript into a named DOM element, which in our case is just a <TD id='name'></TD>; the menu gets inserted in the table cell.
At a minimum, try debugging your javascript bug using Microsoft's script debugger (downloadable from microsoft.com). You should be able to determine precisely why there is a failure; comapre your code to the original nav you started from and carefully pick out what could be different.
The onload events and the PCC are critical to normal function of the portal. Sgutting that off isn't an option, in my mind. If you wanted to, you'd need to do some pretty major surgery on the portal, and thaqt wouldn't upgrade, either.
