Maybe. I had VisualVM running when I got this today (and probably other
days). It would have detected the VM start and possibly made such a
request.
I thought about this possibility, but this doesn't happen every time,
just sometimes. For example, in this case, I started the server, got
the exception traces, and so kill the server. When I restarted it, I
didn't have any problems. VisualVM was running for the entire duration
so if it is interfering, it's intermittent or dependent on something weird.
I guess I'll just keep an eye out for consistent reproducible
conditions. Is there anything that can be done about it? (either on
the VisualVM side, assuming there's a connection, or the GlassFish side?)
