Java.lang.VerifyError with JDK1.3.1_02

Question

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.

Answer 1

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.
