Description Jeffrey K Czyz CLA 2007-11-26 22:43:06 EST 
Suspending and resuming the VM was addressed in Bug 7860.  In the comments, it is stated that either the entire VM can be suspended or individual threads can be suspended, but not both.  I would like to request to have this restriction removed.  I cannot determine if there was a reason why this was necessary.

It would be useful if, when suspended at a breakpoint, one could suspend the remaining threads by suspending the VM (debug target).  This would allow examining call stacks which can be useful for finding concurrency bugs.  Currently, the only other options are:

- suspend all other thread individually, or
- change the breakpoint's suspend policy

The first option is time consuming for programs with many threads.  The second option does not offer the flexibility of resuming individual threads once the VM is suspended.
