ClassFormatError: Invalid this class index 50945 in constant pool in class file

[GoogleCodeExporter]

Hi,

I wanted to test a class with PowerMock wich is quite big (approximately 6800 
lines). I have to use the annotation SuppressStaticInitializationFor to 
suppress some static initialization of this class. I got the error below.

The version of PowerMock is 1.4.11. Javassist version is 3.15.0-GA (I tried the 
3.16.1 too). The operatin system is Windows XP.

If I decreased the size of the class I didn't get the error.

What Java version are you using? Please try upgrading to the latest version of 
PowerMock and see if you get the same issue. If you're using java 7 you must 
use PowerMock trunk and Javassist 3.17.

Hi, thanks for the reply!
I am using jdk1.6.0_30. I tried the latest PowerMock too.
Is it possible that I get this error because the class is too big which I want 
to test?
Thanks,
V.

It could be, I remember there was someone a couple of years ago that had a 
similar problem when the class was huge. If it doesn't work with the latest 
version of Javassist then I think you should post a bug report on the Javassist 
bug tracker.

You can use this option to fix this problem: -XX:-UseSplitVerifier
If you run your test in eclipse : Windows-Preferences-Java-Installed JREs
Select your JDK and click on edit, in the defalut VM arguments add 
-XX:-UseSplitVerifier
I faced a similar problem and it works fine for me
