So what's the trouble?
Thanks a lot.

Printing report that has a parameter with multiple values crashes jvm

I am using BOE XI 4.0 as an unmanaged RAS.
I am able to preview a report that has a string discrete parameter that can have multiple values. If I give it a single value. It previews fine. If I give it an empty string it prints all values which is fine. If I give it two discrete values, it displays just those two.
However, if I try printing the report to a printer:
1 parameter value - prints fine.
2 parameter values - crashes jvm
empty string parameter value - crashes jvm
I would appreciate some direction on how to do this. It works in crystal reports for eclipse.
The test jsp I am using is based off of the samples. The print test jsp is the same as the preview test with the exception of the following code differences.:
preview report.jsp code
// Create a Viewer object
CrystalReportViewer viewer = new CrystalReportViewer();
// Set the report source for the viewer to the ReportClientDocument's report source
viewer.setReportSource(clientDoc.getReportSource());
// Process the http request to view the report
viewer.processHttpRequest(request, response, getServletConfig().getServletContext(), out);
// Dispose of the viewer object
viewer.dispose();
print report jsp code
PrintReportOptions printOptions = new PrintReportOptions();
printOptions.setPrinterName("DELL");
try {
      clientDoc.getPrintOutputController().printReport(printOptions);
} catch (ReportSDKException ex1) {

} catch (Exception ex2) {

Sample code to crash JVM

Hi,
I am working on a program that do not report the stack trace from a crashed JVM (this is reported by customer).
However i do not know how to crash a JVM, using a simple java application, so as to debug the above problem.
Can someone please suggest a simple java application to cause JVM crash (JDK1.4.2.10 or JDK 1.5.x)
Thanks

Hi,
//add the following line anywhere
//credits++ to [email protected]
import sun.dc.pr.PathDasher //[goes to the top alongwith other import(s)]
PathDasher dasher = new PathDasher(null) ;
//The JVM crashes when this line is executed
// This is worrying because even Tiger [5] crashes
Thanks

2 thoughts...
First, player.realize is a non-blocking asyncronous call. You need to wait for the player to enter the realized state before you call start on it.
Second,
player.stop();
player.close();
player.deallocate();
player.realize();
player = null;
Why in the name of God are you realizing a deallocated player? This is probably your problem, because players can't be garbage collected if they're not stopped, and a realized player isn't stopped.
Take out the player.realize() in the above snippet, because that's a memory leak.

TC Keeps backing up until full; then crashes

Myself and my flatmate share the same TCapsule; however whilst he can successfully perform both an initial 80Gb backup via ethernet and then subsequent hourly backups wirelessly - when i try to do so my initial 120Gb backup runs continuously until the 500Gb TC is full - and then falls over.
*Actions to date*
I have reformated the TC twice now with the same result via ethernet backup.
I tried backing up once based upon wireless alone - same result.
I have reinstalled Airport Utility
*Background info*
500Gb Timecapsule, 2 months old as an Apple provided replacement for one that crashed and was within my AppleCare protection plan.
Both of us operate on 10.6.6 with Intel based MacBookPros
Both initially backed up via Ethernet cable, then left TC to operate wirelessly.
It used to work for me, but has failed to do so on the old TCapsule and the new, therefore i suspect it might be to do with my MAC.
I haven't tried re-installing Snow Leapord 10.6 from scratch as yet - but that seems a bit extreme?
Any thoughts, tests, advice or whatever will be gratefully received!
thanks

Hi, and welcome to the forums.

Most likely, yes.
I haven't tried re-installing Snow Leapord 10.6 from scratch as yet - but that seems a bit extreme?
It may come to that, but not just yet.
Start by verifying your internal HD, per #A5 in [Time Machine - Troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html] (or use the link in *User Tips* at the top of the +Time Machine+ forum).
Then do a "full reset" of Time Machine, per #A4 there.
Then try again (via Ethernet if possible).

JDriver for Oracle crashes JVm on solaris

Hi,
I'm using the weblogic jDriver/XA for oracle with oracle 8.1.7 on solaris 2.8.
The weblogic version is 6.1 SP2.
The JVM randomly crashes with this error:
Is the jDriver/XA that comes with weblogic stable ?
Has the jDriver that comes with wlserver 6.1 SP3 fixed this problem ?

We have observed some problems for XA in oracle 817 client. You should use 901 client and 901 jDriver
to talk to 817 database as a solution.

Hi,
I'm using the weblogic jDriver/XA for oracle with oracle 8.1.7 on solaris 2.8.
The weblogic version is 6.1 SP2.
The JVM randomly crashes with this error:
Is the jDriver/XA that comes with weblogic stable ?
Has the jDriver that comes with wlserver 6.1 SP3 fixed this problem ?

JFileChooser crashes JVM - bug basically ignored. What can I do?

See:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7160713
The bug has been marked as incomplete,needs more info, and "Low Prioroty" - Yet there is no mechanism to provide any more information. There is no way to add comments, or vote. The bug brings down the entire JVM with a native crash and it is trivial to reproduce.
I would provide any information that is asked of me - but I need a way to do it. I think I got an email request for info (It's been a while now), but replies to the email bounced, and as noted above the bug page has no way to give feedback.
Use any JFileChooser, click on the "Details" view. Then start clicking on column headings... after a few clicks the JVM crashes. Tested again with 7u6 - still crashes.

This reproduces the problem more reliably for me.

Runtime.exec() crashes JVM

I wrote a program that runs a Perl script repeatedly via Runtime.exec().
Q: Under what circumstances would this procedure silently crash the JVM? I am experiencing this behavior on Linux using Sun's JDK as well as IBM's. There is no error output. The program simply exits. What is causing this? And, how can it be avoided? If there is a way to recover from whatever problem is occurring, that would be ideal.

Thanks jschell! Your input is helpful.
I suspect that case #4 is in play here. When I run my program with the "-Xrs" switch, "Terminated" is outputted just before the JVM exits. Is there any way to intercept the signal to terminate from the child process before the JVM exits?
NOTE: I am not running Runtime.exec() concurrently and I am explicitly destroying each Process after process.waitFor(). Also, I tend to watch the linux "top" output to confirm that only one Perl process is running at a time. I have tried various versions of a "runCommand" method. The current version spawns no additional threads:
public static int runCommand(String[] command) throws InterruptedException, IOException
          ProcessBuilder builder = new ProcessBuilder(command);
          builder.redirectErrorStream(true);
          Process process = builder.start();
          InputStream input = null;
          InputStream error = null;
          OutputStream output = null;
          BufferedReader reader;
          String line;
          try     {
               input = process.getInputStream();
               error = process.getErrorStream();
               output = process.getOutputStream();
               reader = new BufferedReader(new InputStreamReader(input));
               while ((line = reader.readLine()) != null)
                    System.out.println(line);
               return process.waitFor();
          finally
               close(output);
               close(error);
               close(input);
               process.destroy();
          }

BufferedImage.createGraphics crashes JVM

Hi,
I want to add some annotations such as lines, text into an image loaded into a BufferedImage. The way I do this is like this:
BufferedImage aBufferedImage = new BufferedImage(cm, raster, false, null);
Graphics g = aBufferedImage.createGraphics();
g.draw .... etc.
ImageIO.write(aBufferedImage, "jpg", new File(inFileName));
However, JVM crashes with message like these:
An unexpected exception has been detected in native code outside the VM.

Note that I never create any AWT or Swing component. The program is supposed to generate dynamic images inside a server and send images to clients.
Has anybody experienced this? Any clue why it happened?
Thanks!

Collect -h crashes JVM

Is this a bug, or I did something wrong?

Thank you for the report! Unfortunately I don't have access to a Niagara-2 system right now.
I tried to run a similar test on Niagara-1 system, but it did not help to reproduce the problem.
Probably it is important to use JDK 1.6.0_07 (I have JDK 1.6.0_06 on my Niagara-1 system),
or the problem is caused by "-h ecdm,10007" option. This type of HWC is not available on
Niagara-1 system, only these 2 are available:
Well-known HW counters available for profiling:
insts[1],9999991 (`Instructions Executed', alias for Instr_cnt; events)
Raw HW counters available for profiling:
Instr_cnt[1],1000003 (events)
I'll try to find a Niagara-2 system and let you know if I see the same problem.
BTW, can you try to run the same test with JDK 1.6.0_06?
Thanks,
Nik

Elements 10 full backup crashes computer @ ~70%

I am running Elements 10 on Windows 7. I am trying to do a full backup of a catelog and it crashes my computer somewhere between 60 and 80% complete. I left the computer overnight so it isn't just "taking a long time".
I have successfully done backups in the past using Elements 10 backup on this computer.
Tried it to the local drive as well as a USB Drive. Nothing else running at the time. Done a catalog repair (no errors found) as well as an optimization.
Elements 10 was the first version I had so shouldn't be a catalog conversion issue.
Any ideas?
Thanks.

Did you tried on the different locations of the hard drive, sometimes in the specific location there is a limited perssimison issue.
Also, check if you have any videos on your catalog, if so please try to move them into a different catalog and try only with images.

Help! Crashing JVM while doing SELECT statement through JDBC-ODBC bridge

Hi everyone,
Help please. I am working on a project on my own computer using the jdk version 1.5.0_04.
The project involves running a select on a Microsoft Access 2003 database via the JDBC-ODBC bridge. The database is registered in the ODBC database sources, and it works fine in those other projects.
Yet, when I'm running similar code in this project, it crashes the Java Virtual Machine. I get the following in a log file:
# An unexpected error has been detected by HotSpot Virtual Machine:
# EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x7c901010, pid=2308, tid=1364
# Java VM: Java HotSpot(TM) Client VM (1.5.0_04-b05 mixed mode, sharing)

The code that is causing the problem is in the class shown below. It is in the method getBoxScoreFromDB. When it attempts to run the first select statement, it causes the crash that I showed above.
The connection is set up by the calling class. The calling class constructs a LUDatabaseWorker, sets the necessary parameters (dbURL, driver class, username and password), and calls the openDBConnection().

its because you use hungarian notation - that was the hollywood squares answer.
It looks like a bug in either the ntdll or the JdbcOdbc dll, so I'd see if you can't isolate the problem (like using a smaller bit of code) and file a bug report. Find out exacty what your sql statement is which causes this to crash - hint : line 215

After AttachCurrentThread: Calling back to Java method crashes JVM

Hi,
so I managed to get my multithreaded native code being invoked from a Java program.
However, as soon as I try to invoke a Java callback from native code not running in the main thread, the program segfaults. Here's my code:
// in the main thread, I store a pointer to the JVM that invokes this code
    if (env->GetJavaVM(&jvm) < 0) {
        std::cerr << "JNI ERROR: Failed getting reference to Java VM" << std::endl;
        return;
    assert (jvm != NULL);
// in some other concurrently running (native) thread:
    JNIEnv *env;
    if (jvm->AttachCurrentThread((void**)&env, NULL) != JNI_OK) {
        std::cerr << "ERROR: Could not attach event thread to JVM" << std::endl;
        return;
    assert (env != NULL);
    assert (connector != NULL);
    assert (focusEventCallback != NULL);
    // the following line segfaults
    env->CallVoidMethod(connector, focusEventCallback);"connector" is a POJO, focusEventCallback the jmethodID referencing the Java callback.
Am I missing something?
Thanks in advance,
Matthias

Getting that reference inside the thread where I use it didn't work, because the class lookup failed (ClassNotFoundException).Which means your code was wrong, not that it wouldn't work.So, what in particular was wrong about my code? Here is the section of the code that did not work, because the class lookup failed:
    JNIEnv *env = NULL;
    // "import" the native user level thread as a Java thread in the JVM
    if (jvm->AttachCurrentThread((void**)&env, NULL) != JNI_OK) {
        std::cerr << "JNI ERROR: Could not attach X11 event thread to JVM" << std::endl;
        return;
    jclass connectorClass = env->FindClass("de/dfki/km/mydesk/nativeInterfaces/linux/NetWmConnector");
    if (env->ExceptionOccurred()) {
        env->ExceptionDescribe(); // will output ClassNotFoundException
    }The same code works inside JNI_OnLoad.
Well, an assertion is supposed to do that: Terminate the program if there is a condition that would stop the program from operating properly. The crashes I was talking about are segmentation faults. A failing assertion is not a crash, it will just terminate the program with an "assertion failed" message.You are not writing a C/C++ app. You are running some code in a shared library that is run from a VM.
Very different.
I haven't tried it but I am rather certain that if you cause an assertion failure that you are going to see a crash. So far as I know the only exit mechanism that doesn't cause the VM to crash explicitly is a system exit call. And that probably shouldn't be used either (not normally.)Well, as far as I know, assert() sends an abort signal and terminates the process (which is the VM in this case). I probably overused assertions in that I used them to probe for runtime errors, not for programming errors. I'll remove them from the retail code anyway, so for now, it's just fine that the program terminates if something goes wrong. It helps locating the offending LOC.

IE crashing jvm.dll - hyperthreading

I have a web application that is loading an appletto create a sub menu. The applet refreshes and sporadically crashes internet explorer. I cannot determine the crash because it is on some machines. I got a process dump of IE from Windows debuging and MS support told me that the jpiexp32.dll was crashing the JVM. The errors are always sharing violations, 0xc0000005.
Are there any issues with JVM and hyperthreading CPU's
What logging or debugging can I enable on the jvm to get more info to post to support.

Rman full backup, crash and full restore?

Hi,
I try to implement a simple backup and restore process with rman. Ok, with rman it's not simple. ;-)
My aim is to backup a database with a full backup and restore it from this backup, for example when it crashes.
Ok, for creating the backup I use this rman script:
run
allocate channel t1 type disk;
backup incremental level 0 format 'PATHTOBAKFILE' database;
release channel t1;
The result is a 1GB large backupfile.
Now I delete the whole database and create a new one to simulate a crash.
After this is done, I want to restore the state of the database which is frozen in the backupfile.
Therefor I use the following rman script:
run
allocate channel t1 type disk format 'PATHTOBACKUPFILE';
shutdown immediate;
startup mount;
restore database;
recover database;
alter database open resetlogs;
release channel t1;
Now rman tells me an error:
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: Fehler bei restore Befehl auf 04/09/2008 10:24:59
RMAN-06026: Einige Ziele nicht gefunden - Recovery wird abgebrochen

RMAN-06023: Kein Backup bzw. keine Kopie der Datendatei 2 zum Wiederherstellen gefunden
RMAN-06023: Kein Backup bzw. keine Kopie der Datendatei 1 zum Wiederherstellen gefunden
In english: No backup or copy of datafile X where found for restore.
I think the backup/restore possibilities with rman are very complex and I don't exactly understand which is the right backup strategie. I'm not an oracle specialist. Maybe someone can give me a hint.
My program should backup the database full, differential and incremental and also restore only by using the given backupfiles. So I want somethink like Point-In-Time recovery, but rman should use the time-point of the given backupfile. And this backupfiles are stored outside oracle, e.g. on a server or somethink like this.
Thanks a lot for help.
Best regards,
Ronny
