JFR integration

[Jonathan Ross]

Hello all,

Apologies if this has been discussed before, I am new to this list...

I have been experimenting with virtual threads in JDK 20, and took a look
at some flight recordings. It would appear that events recorded on virtual
threads have empty 'Event Thread' fields, and that carrier threads don't
have names.

My copy of jmc (Azul Mission Control 8.3.0) currently renders all virtual
thread events on a single nameless thread in the thread view, which, as it
hopefully goes without saying, makes it much harder to analyze program flow
than when using a ThreadPoolExecutor or a ForkJoinPool.

Is there a reason for the blanks?  Or is Mission Control at fault?

Thanks in advance,

Jonathan Ross
