This looks good. I've posted a couple of nits/questions though.
One more question. Why these tests are failed with the UT enabled? Or maybe
this was wrong assumption?
test/hotspot/jtreg/vmTestbase/nsk/jdi/ClassPrepareEvent/referenceType/refType001.java
line 134:

Nit: Would it make sense to uncomment this log message? How many events are
normally printed?
test/hotspot/jtreg/vmTestbase/nsk/jdi/ClassPrepareEvent/referenceType/refType001.java
line 277:

As I understand the call to `eventHandler.interrupt()` is not needed now
because now the `eventHandler` is expected to finish by itself when one of the
events is received: `VMDeathEvent` or `VMDisconnectEvent`.
