Still crashity crashing

[Attila Szegedi]

I too managed to crash it yesterday, but it turned out I accidentally  
emitted invalid bytecode from ASM - I forgot to end the binary name of  
a class with semicolon in method signature of an invokedynamic  
instruction. Amazingly, neither ASM nor the verifier caught it.  The  
crash message was something along the lines of "ShouldNotBeHere" or  
similar :-)

All I want to say is, in my case it crashed because I fed it garbage.  
Not necessarily true in your case, but worth doublechecking what you  
do (knowing you, you probably did it anyway before posting).
