Subject [jira] Commented: (HARMONY-1769) [drlvm][jvmti] Unexpected exception in JVMTI mode
Date Tue, 24 Oct 2006 19:07:18 GMT
    [ http://issues.apache.org/jira/browse/HARMONY-1769?page=comments#action_12444461 ] 
Gregory Shimansky commented on HARMONY-1769:

Probably because eclipse compiler generates this swap bytecode while Sun javac could be generating
the code which doesn't cause JIT bug.

I have another question. The attached patch only adds a function prototype to the header.
Where is the trick?
