Re: RFR: 8260589: Crash in JfrTraceIdLoadBarrier::load(_jclass*)

Of course, but I need some time to backport it to 8 and 11 to verify if our applications can work normally
since your changes involve jfrTypeSet whose logic has some difference between 8/11 and upstream.

Thanks,

Hi Denghui,

I did not manage to find a solution that would could reduce verbosity, but i did find one, although a bit involved, that lets us keep it local to and integrated in the core of JFR itself.

Can you do a test run with this suggestion to see if it works for you?

Thanks
Markus
