Looking at the Agent_OnLoad() code in debuginit.c of libjdwp, I see that both the METHOD_ENTRY and METHOD_EXIT are listed as required, but I don't see where they are ever enabled in the agent. In the J9 JVM making it possible to enable these events has severe performance penalties. Since the events are not enabled in the JDWP agent, simply reserved, we were hoping you'd be open to removing the reservation of the capabilities.

If the JDWP agent never enables these events then it shouldn't need to obtain the capabilities. I have a vague recollection that they are enabled when single stepping, are you sure this isn't the case? Have you run the tests with without enabling the capabilities?
