problems with step debugging

[Jochen Theodorou]

thanks for reacting John,

now... yes, invokedynmic doesn't have the problem, so it might be a 
problem with invokestatic.

The problem with the thing simply is, I don't know what bytecode is 
supposed to be correct or if there is actually a problem with the JVM. I 
kind of doubt the later, since it doesn't seem to be version related. So 
if it is a bug, then it would most probably be an old one.

If I know how it is supposed to look like, I can change our compiler to 
emit the line number information exactly where suggested and then see if 
it works. But for that I missing that information :(

bye Jochen
