Because Java defaults to -fnon-call-exceptions. Add 
-fno-non-call-exceptions and it will work. It looks to me like the 
REG_EH_REGION check in postreload-gcse.c is bogus. We can have these 
notes here with -fnon-call-exceptions, and we will have to do something 
about them. Perhaps just ignoring insns with a REG_EH_REGION note will 
work, which appears to be what gcse.c does. I haven't haven't really 
looked at the code to see if this is the proper solution though.
