So you want, postExceptionEvent instead of post_exception_event.  What 
about the two native calls should they be sendEvent and checkCatch.  
Also do you want the variable names changed to throwMeth, catchLoc etc?  
And while I'm at it, should it be funtion() or function () in java files 
outside of classpath, I think I've seen both?.  I'm sorry to keep asking 
about/screwing this up but I find it can be a little confusing to know 
which conventions to use sometimes.

Other than these is this ok to go in?
