Looks like a bug in the jgroups subsystem. It looks like the threading subsystem starting returning "protected" decorators, which prevents the jgroups subsystem from accessing the underlying thread pool properties. I'll post a workaround - basically configure the timer directly in jgroups.

Michal, we're waiting for 7.0.1 upgrade to fix this?
this wasn't very critical. I used Paul's workaround but now it should be fixed. closing.
Michal, you should update the resolution. Won't Fix is probably the best option.
