This enhancement adds ForceEarlyReturnXXX support for virtual threads. The spec
defines minimal support that the JVMTI ForceEarlyReturnXXX can be used for a
virtual thread suspended an an event.

I fully understand why authors of (truly excellent, in your case!) advanced
serviceability agents would see any feature that could affect their area of
interest as a problem, but you surely understand that our responsibility is
toward a far larger ecosystem. Even the ultimate restriction —

agent, which is not true. Instrumentation

Because the discussion of this JEP has veered in many directions, let me
summarise where we are:
This JEP proposes to emit a suppressible warning when a JVM TI or Java agent is
loaded into a JVM sometime after startup through the Attach mechanism.
