Henrik,
A simple one would be to release the final Exceptions code as an update, and issue new VMs.
One reason why we're a bit hesitant to do this is that we are SOOOOOOO close to having a J3 for everyone to play with - as of today, j3 did run approx. 3922 bytecodes before locking up on MacOS, due to a disagreement between Ian and MacOS what the "right" stack frame is (of course, Ian is right and MacOS is wrong...)
Doing the exception modifications would require several changes in the j3 and right now we want to look at porting j3 to a number of key platforms. So I wouldn't bet on the exception modifications in the immediate future.
