Looking at the Agent_OnLoad() code in debuginit.c of libjdwp, I see

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?
