Comment 3 Paul Ferraro 2011-07-19 16:40:47 UTC 
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?
Comment 9 Michal Linhard 2011-08-03 15:39:20 UTC 
this wasn't very critical. I used Paul's workaround but now it should be fixed. closing.
Comment 10 Galder Zamarreño 2011-08-04 10:15:40 UTC 
Michal, you should update the resolution. Won't Fix is probably the best option.
