Looks good!

Thanks for making the change.

On a positive note I think this would now show that the conversion from VMop to direct handshake was actually much simpler than might have been thought. :)

I'm not sure when the repo fork is happening, so am unclear whether this will head to the right repo in time. :)

Thanks,
David

Hi David and Serguei, (Dan feel free to chime in)

Honestly I think I'd like to see things reverted to the use of calling_thread as done for the VMOperation previously. We know it is functionally correct and it should also have the same performance profile.

Done:
http://cr.openjdk.java.net/~rehn/8247248/v2/webrev/

Passes: hotspot jdi/jvmti testing, running mach5.

I'll push tomorrow morning if test is ok and you all are happy (+- nits). (and no objection to break the 24h rule) I started this patch with reverting "8242425: JVMTI monitor operations should use Thread-Local Handshakes".
And work my way forward.

Thanks, Robbin

Issue:
https://bugs.openjdk.java.net/browse/JDK-8247248

Local testing of JDI/JVMTI and t1-5.
(no real crash so there is nothing to reproduce)

Thanks, Robbin
