Sorry, the fix is not going to work correctly.
The first vm.suspend() has to be before the switch statement to work for all 3 cases.
Thanks,

I prefer to suspend/resume in all cases, so we avoid all these unexpected failures.

It should be failure anyway if we managed to enable events, so we don't expect to really enable anything in these cases.However I agree that adding suspend/resume shouldn't make it worse, just possible cleaner log (in very rare cases also). If you feel it is need I will just add suspension for all cases.

Does it mean, you did not fix cases 0 and 2 because the related failures have never been observed?

Test should fail in cases 0 and 2 with IllegalThreadStateException if we can enable events. Such failures should be easily identified by reading logs.

Hi Leonid,
The fix looks good in general.
You missed to explain that the suspend/resume are added to avoid actual generation of event that cause this issue.
The reason is that these events are not actually required.

316 case 1: 317 vm.suspend(); ... 336 vm.resume();
Q: Why is only in case 1 suspend/resume used?
What about cases 0 and 2?
Thanks,

Hi
Could you please review following fix which suspends debugger VM while enabling/disabling events.
All changed tests fail intermittently getting unexpected events instead of breakpoint used for communication between debugger/debuggee VM. The tests request different events and verify request's properties but don't process/verify events themselves. Test doesn't aware if events are generated or not. The vm suspension doesn't affect JDWP native agent and it still should get and verify JDWP commands.
