-----------------------------------
Summary: JMX InstanceAlreadyExistsException when restarting web
distribution on WebSphere
Key: SM-2161
URL: https://issues.apache.org/jira/browse/SM-2161
Project: ServiceMix
Issue Type: Bug
Components: servicemix-core
Affects Versions: 3.4.1
Reporter: Gert Vanthienen
Assignee: Gert Vanthienen
Fix For: 3.4.2
When registering an MBean, WebSphere is appending additional information to the
MBean's ObjectName. When trying to unregister the bean at shutdown, we're not
taking that into account, leaving the old MBean lingering around and causing
this InstanceAlreadyExistsException when restarting the webapp.
