[jboss-jira] [JBoss JIRA] Updated: (JGRP-993) InstanceNotFoundException when destroying jchannel (TP.ProtocolAdapter not found in MBean server)

InstanceNotFoundException when destroying jchannel (TP.ProtocolAdapter not found in MBean server) ------------------------------------------------------------------------------------------------- Key: JGRP-993 URL: https://jira.jboss.org/jira/browse/JGRP-993 Project: JGroups Issue Type: Bug Affects Versions: 2.6.9 Environment: Windows Reporter: Stefan Anzinger Assignee: Bela Ban Priority: Minor Fix For: 2.6.14 When using shared transport with org.jgroups.jmx.JChannel there occurs a javax.management.InstanceNotFoundException when destroying the cannel. It has no major impact as the exception is caught and not thrown outside of jgroups. Unfortunately the exception is logged as error where obviously is no error.
