Java.lang.VerifyError in code generated by Prototype 1.2

I managed to get a java.lang.VerifyError from a class generated by prototype 1.2. A short test case follows: (It looks like the compile knows it can call .intern() on the result of the
?:, but the verifier thinks the bytecode does something wrong..)
import java.util.Stack;
public class Case
public static void main(String[] argv)
Stack<String> bar = new Stack<String>();
String foo;
// Compiles, but causes verify error
foo=(bar.empty()?"":bar.peek()).intern();
// The following two work fine
foo = (bar.empty()?"":bar.peek().intern());
foo = (bar.empty()?"":(String)bar.peek()).intern();

Hi,
I've noticed the same behaviour (java.lang.VerifyError) with code that uses extra parentheses on the return
statement, i.e.:
return(object);
instead of:
return object;
Interestingly, parentheses also seem to affect your above example. If I change it as follows:
public class TestGenericsBug
public static void main(String[] argv)
Stack<String> bar = new Stack<String>();
String foo;
// Compiles, works fine
String tmp = bar.empty()?"":bar.peek() ;
foo = tmp.intern();
// The following two work fine
foo = (bar.empty()?"":bar.peek().intern());
foo = (bar.empty()?"":(String)bar.peek()).intern();
The code compiles and runs. If, however, extra parenteses are added:
package test;
import java.util.Stack;
public class TestGenericsBug
public static void main(String[] argv)
Stack<String> bar = new Stack<String>();
String foo;
// Compiles, but causes verify error. Extra Parentheses ?
String tmp = ( bar.empty()?"":bar.peek() );
foo = tmp.intern();
// The following two work fine
foo = (bar.empty()?"":bar.peek().intern());
foo = (bar.empty()?"":(String)bar.peek()).intern();
The bug is back!

Java.lang.VerifyError - another cause

I just banged my head against this error for half a day before figuring it out.
I was deploying some code compiled under 1.2 into a 1.3.1 environment and kept getting this error when I tried to load a certain class:
java.lang.VerifyError: (class: com/athensgroup/autoweb2/databeans/FileTree, method: fillFileTreeForm signature: (Lcom/athensgroup/autoweb2/forms/FileTreeForm;)Z) Expecting to find integer on stack
Real helpful, huh???
Turns out the offending method has a couple of lines of code like:
boolean foo = false;
foo += "some string";
Apparently this got by the 1.2 compiler, but created something the 1.3.1 loader didn't like.

interesting
it shouldn't do like this
it is a very strange behaviour
thanks for informing

Hi,
(2) Node 2 has java version:
java -version
java version "1.4.2"Do you run this command as applmgr user? If yes, did you source the application env file?
Could anyone please share such an issue faced before and provide resolution as to what's wrong in here in node 2?Why the java version is different on the both nodes?
Thanks,

Java.lang.VerifyError - Incompatible object argument for function call

Hi all,
I'm developing a JSP application (powered by Tomcat 4.0.1 in JDK 1.3, in Eclipse 3.3). Among other stuff I have 3 classes interacting with an Oracle database, covering 3 use cases - renaming, adding and deleting an database object. The renaming class simply updates the database with a String variable it receives from the request object, whereas the other two classes perform some calculations with the request data and update the database accordingly.
When the adding or deleting classes are executed, by performing the appropriate actions through the web application, Tomcat throws the following:
java.lang.VerifyError: (class: action/GliederungNewAction, method: insertNewNode signature: (Loracle/jdbc/driver/OracleConnection;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;I)V) Incompatible object argument for function call

 at javax.servlet.http.HttpServlet.service(HttpServlet.java:853)
 at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:247)
...The renaming works fine though. I have checked mailing lists and forums as well as contacted the company's java support but everything I have tried out so far, from exchanging the xerces.jar files found in JDOM and Tomcat to rebuidling the project didn't help.
I just can't explain to myself why this error occurs and I don't see how some additional Java code in the other 2 classes could cause it?
I realize that the Tomcat and JDK versions I'm using are totally out of date, but that's company's current standard and I can't really change that.
Here's the source code. I moved parts of the business logic from Java to Oracle recently but I left the SQL statements that the Oracle stored procedures are executing if it helps someone.

After further googling I figured out what was causing the problem: in eclipse I was referring to external libraries located in eclipse/plugins directory, whereas Tomcat was referring to the same libraries (possibly older versions) in it's common/lib directory.

DataDirect driver throws java.lang.VerifyError

WebLogic: 8.1.5 
OS: Windows server 2003 
DataDirect: 3.50.0 (JDBC driver) 
 
I have a web application that use its own JDBC driver management (DataDirect 3.50.0). When I moved from WebLogic 8.1.3 to WebLogic 8.1.5 the application crash with stuck dump below on exception java.lang.VerifyError. 
 
 
Any ideas why this happened ?
 
 
Thanks,

First, thanks a lot for the quick reply. I appeciate this. 
 
1. You are right, com.mercury.jdbc is a repackaging of DataDirect's driver. 
2. Full Stack dump: Ok, I suggest yo first contact DataDirect and show them
this exception. However, I have a suspicion that your
version of the driver has some conflicting versions of
some internal security classes from the versions of the
DataDirect drivers that we ship, rebranded as BEA drivers.
So, try going to your server\lib directory, and renaming
the wlutil.jar, wlbase.jar, and wlsqlserver.jar so WebLogic
won't use them. Let me know if that makes your odd exception
go away. Also, you might consider using our drivers. Get
the latest driver package and you will have DataDirect's
latest and best, including all the BEA-found bugs fixed.

The guys over in the J2EE forum came with this answer. Please note that they refer to Jdeveloper 9.0.3.
I don't really know how to interpret that, as the RC2 Jdeveloper is 9.0.2.7.86, but anyway, her goes:
<snip>
It seems like you are using JDeveloper 903, is that right?
Select Help->About from the Jdeveloper menus
If you are using Jdeveloper 903, read on:
This is a known issue. 903 Jdeveloper is bundled with J2EE ORB (IIOP.jar) from Sun to allow EJBs communicate using RMI/IIOP. In addition, we also have Visibroker ORB (VBJORB.jar) in the classpath. Sun has implemented CORBA 2.3.1 specification and Visibroker I believe has implemented CORBA 2.3.0 spec. The signature of one of the methods in class org.omg.PortableServer.AdapterActivatorPOA has changed between the two releases and hence the problem.
We are trying to move away from Visibroker ORB and have requested OLAPI team to remove all dependencies on Visi ORB. Although there is no known dependencies on it, there seems to be dependencies because the idl compiler (from Visibroker) is inserting referces to Visibroker code.
To work around :
Remove/rename iiop.jar file in ORACLE_HOME/J2EE/HOME directory. Be warned that EJB's wont work if it is renamed or removed.
This should only be considered as a temporary work around until we decide our next steps.
</snip>
Use at own risk..
The error reported in this thread disappeared with this workaround, but unfortunately I got another one:

Upgrading from j2sdk-1_4_2_07 to jdk-1_5_0_06 java.lang.VerifyError

HI,
i'm trying to upgrade my application from jdsk 1.4.3.07 to jdk 1.5.0.06.
The applications works fine compiled with 1.4 and run with 1.4 and 1.5, but where i try to compile and run with 1.5 i received a:
java.lang.VerifyError !!!
I'm use log4j 1.2.13 and gnuregexp as external library.
Has someone an idea ?
thanks in advance
Carlo Mossa ([email protected])

Try to use -target 1.4 option of javac.
Default mode in jdk1.5 is -target 1.5 and it generates classes which are not supported by 1.4.

You can't inherit from a final class.
So - are you trying to inherit from a final class?

Java.lang.VerifyError when using ant 1.6.2

In short, I get the VerifyError when deploying my .ear in Weblogic 8.1 SP2. I have nailed down the issue to this:
I compile all my code using Ant 1.6.2. If I package the code up using ant 1.6.2 I get the VerifyError. If I pacakge the code up using ant 1.4, all is well. Note that when I deploy the 1.6.2 packaged ear file on Windows, all is well also.
During the ant package target I assembly the war and ear using the core war and ear tasks.
We are using precompiled JSPs in the war file. It seems that WL8.1 wants to recompile the JSP file. I am not sure why - the ant 1.4 packaged ear does not want to recompile the same JSP.
The detailed error is:
Servlet class jsp_servlet._portal.__capitalmarketsoverview for servlet /portal/CapitalMarketsOverview.jsp could not be verified.
java.lang.VerifyError: (class: jsp_servlet/_portal/__capitalmarketsoverview, method: _jspService signature: (Ljavax/servlet/http/HttpServletRequest;Ljavax/servlet/http/HttpServletResponse;)V) Incompatible object argument for function call.>
Any help is appreciated,
Harry Duin

Hello,
I could not find an easy way to get the wls version of ant to start using the tasks you mention from ant 1.6.2.
I tried defining the tasks using taskdef and also adding them to wls ant.jar and updating the deafult.properties file but the ant complained about unexpected elements in the build.xml file where I added the new tags (e.g import)
If your really up against it you can try adding wls tasks to ant 1.6.2, they are listed here:
http://e-docs.bea.com/wls/docs81/toolstable/ToolsTable.html#1009580
Although I could not located exactly which jar they are in. Good luck.

Upgrade to 10.1.2.3 now getting java.lang.VerifyError using rwrun.sh

We recently upgraded our Application Server/Forms and Reports to Oracle 10.1.2.3. We have one application that uses a python script and calls rwrun (or rwrun.sh) from Generic Apache (not Oracle's Apache).
We are now seeing the following error from the rwrun.sh command:
ERR REP-0069: Internal error
java.lang.VerifyError: class org.omg.PortableServer.AdapterActivatorPOA overrides final method .
This use to work with Oracle 9.0.4 I opened a Service Request with Oracle since I was also having problems running this from the command line. At that point I had to open up the $OH/diagnostics/config/registration directory to world write access.
Now that I got past that, the command line rwrun works, but the call from the python script using the generic apache doesn't.
Oracle wouldn't help since this is custom code.
Any suggestion.
Thanks,
Shirley

Java.lang.VerifyError with JDK1.3.1_02

Hi all,
I was using a third part ".jar" in my application and I started getting a java.lang.verifyError. I was wondering what are the various reasons that can cause this error to show up. I have jotted down the possibilities I can think of, but due to lack of documentation from the Java team at sun, I am not too sure. If anybody can cross-verify these and can provide feedback, it would be great.
Reasons for java.lang.VerifyError :
1) You compiled your code which uses ABC.java in package1 and while running it you used package2 instead of package1 which also had ABC.java.
2) You call a method in your code which accepts say a String[] array, but at run time what you pass to the method is merely a String - Although this kind of code should not compile at all, but again what class you use at compile time and runtime can be different and can cause this to happen.
Any other additions / Corrections are welcome.
Thanks.
Vivek.

Hi, Do you get any message / stack trace to find out
where it happens .I have actually fixed the problem now, basically the code was compiled with one xerces.jar and at run time a different jar with the same class files was getting included. What I wanted to find out is that are there other reasons for getting this VerifyError - coz the Java API does not mention anything about what conditions can cause this to occur.
Thanks.
Vivek.

Any way around java.lang.VerifyError in JUTableSortModel.enableColumnSortin

Hi,
(JDeveloper 10.1.2) I have created a ADF Client application on top of an POJO business service. The application contains a tabbed pane. The first tab is based on a master data control binding, the second on its details-collection data control - as a JTable.
When I run the application (from within JDeveloper) , I get a Fatal Exception from the JVM:
Exception in thread main
java.lang.VerifyError: oracle.jbo.uicli.jui.JUTableSortModel
     at oracle.jbo.uicli.jui.JUTableBinding.getControlModel(JUTableBinding.java:106)
     at oracle.jbo.uicli.jui.JUPanelBinding.bindUIControl(JUPanelBinding.java:817)

     at amis.view.tabbedPane.FortuneForm.setBindingContext(FortuneForm.java:467)
     at amis.view.tabbedPane.FortuneForm.main(FortuneForm.java:375)
When I swap the JTable for some simple JTextFields, the code runs ok. However, I really like to have a Table. Does anyone have any clue or workaround for this situation? Since the exception originates within the ADF library code, I do not see too many options myself.
thanks for your help.
Lucas

OK, I have been too hasty once more.
When I create a simple ADF BC Model, drag a ViewObject's Data Control as Table to the ADF JClient pane and run the application, I get the same fatal exception. So it has nothing to do with the Business Service technology, it is a generic ADF JClient JTable issue.
Question is still: what can I do to get rid of it? Is it just my installation, project setup? Should i create a fresh JDev install? Is there a patch?
Any help is very welcome.
