The changes for 4909274 in b32 to allow the VMStart event be requested have a
bug which results in a potential duplicate requestID or potentially causes
the JDWP agent to crash.
The issue is not serious as we aren't aware of any debuggers or tests that
request the VMStart event. In addition, prior to b32, requesting this event
always caused the JDWP agent to terminate with a fatal error.
