This looks like a miscompilation of some kind - as if the "if (! 
(loadFactor > 0))" was incorrectly constant-folded to "true" - (there 
was a bug like this on the mainline that was fixed recently). However it 
would be very strange if this did not show up with a simple test case 
that called the Hashtable constructor.

I would say that gdb is playing tricks on you if it wern't for the 
actual exception being thrown. Perhaps try again with the latest gcc 
tree to see if it still occurs. You can also try building libgcj with 
GCJFLAGS=-g to get a non-optimized build.

Right. In any case, code from libgcj should never get inlined into your 
application binary.
