6559156: My favorite defect

[rgougol at email.sjsu.edu]

Hello everybody,

I am trying and hoping to remove the defect 6559156,
http://bugs.sun.com/view_bug.do?bug_id=6559156. In fact, I am supposed to have a
contribution by the next two weeks as a requirement of my course CS286: Open
Source Development, http://www.horstmann.com/sjsu/cs286/gs.html. Will I have the
chance? If not, would you provide me an alternative defect removal or RFE as
soon as possible. 

My assumption is that the defect exists in file /src/share/vm/opto/subnode.cpp
within optimizations of integer cmp. I wish I could trace the server compiler at
this file using GDB. However, while trace virtual machine launcher of openjdk 
fastdebug with GDB, it produces a new process and then goes beyond the control.
Can you tell me how I may trace the C2 optimizations with GDB and how to put the
break point for the new process that is produced using GDB?

Sincerely,
