LocalVariableTypeTable?

I resolved my problems with the LVT via some ugly hacking. But now
I'm getting an LVTT problem:

java.lang.ClassFormatError: LVTT entry for 'classes'
in class file org/junit/runner/JUnitCore does not match any LVT entry


Looking through the source files I don't even find the string 
LocalVariableTypeTable.
Does BCEL handle the LVTT?

I also can't find the API javadocs.

Any ideas?
