[ https://issues.jboss.org/browse/ISPN-8729?page=com.atlassian.jira.plugin.... ] Radim Vansa commented on ISPN-8729: ----------------------------------- It should not block by design, be it used from server or from application. Such behaviour would be a bug in given component: is your question about making sure such situation is detected (in testsuite)? Actually right now it can block when running out of credits in JGroups: 4.0.4 already provides a [non-blocking variant|http://belaban.blogspot.cz/2017/06/non-blocking-jgroups.html] but this is not used in our configuration yet - I should probably add that to the PR (as a separate commit). -- This message was sent by Atlassian JIRA (v7.5.0#75005)
