googling around I found these two posts in our archives:

rpmfind.net/tools/Kaffe/messages/0238.html
rpmfind.net/tools/Kaffe/messages/0239.html 

I'll cite from Godmar's response:

"this error nsg most likely indicates a segfault within a section of 
code where interrupts are disabled. 
If the code segfaults there, it will try to throw a nullpointerexception 
which will trigger this assertion failure. 
No exceptions should ever be thrown from code that executes in a section 
in which interrupts are disabled."

So you seem to have found a bug in kaffe's virtual machine code. 
Congratulations :)

You might want to read FAQ/FAQ.debugging and FAQ/FAQ.jsignal if you want to 
fix the bug.
