Bug ID: 56369
Summary: BaseModelMBean does not clean-up attributeBroadcaster
in removeNotificationListener()
Product: Tomcat 7
Version: unspecified
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
Assignee: dev@tomcat.apache.org
Reporter: lor...@bitronix.be
BaseModelMBean.addNotificationListener() registers the listener on
attributeBroadcaster, while BaseModelMBean.removeNotificationListener() fails
to clean that up.
The end result is a memory leak that is very apparent when you embed directly
in your WAR file jmxremote_optional.jar as the
com.sun.jmx.remote.opt.internal.ArrayNotificationBuffer$BufferListener'
classloader cannot be garbage collected which end up depleting the perm gen
merely after a few redeploys.
