In this case I think it's more an issue with the underlying application, but perhaps there could be a more broad way of signalling that a jvm is ready for attachment. There's an old issue I had found on the RH Bugzilla (from 2013) that details a similar instance to this, although it's with VisualVM instead of JMC: https://bugzilla.redhat.com/show_bug.cgi?id=1037970. I've also found similar stack traces through Google suggesting other people have encountered similar failures due to dynamic agent attachment, so I think it's more an issue with JBoss EAP than anything.
