The nsk/jvmti/RedefineClasses/StressRedefine crashes with the following error:

# A fatal error has been detected by the Java Runtime Environment:

The event log about internal exceptions shows that previously it failed to load a class, i.e. a ClassFormatError has been thrown:

Event: 14.747 Thread 0x055d9000 Exception <a 'java/lang/ClassFormatError': Method "append" in class MyClass has illegal signature "dd"> (0x3a2628f8) thrown at [\share\vm\classfile\classFileParser.cpp, line 1618]
Event: 14.771 Thread 0x057e1800 Exception <a 'java/lang/ClassFormatError': Truncated class file> (0x3a2d09f8) thrown at [\share\vm\classfile\classFileStream.cpp, line 30]

The log file at that point gives some cryptic error message:
