Sergey commented on AMQ-3959:
-----------------------------
The undeployed web application remain in memory until you re-deploy or
re-start. After re-start the reference is replaced by the new StringArrayEditor
class loaded by the new WebAppClassLoader.

> Create a web application which connects to an ActiveMQ standalone server,
> package activemq-core.jar into WAR under WEB-INF/lib.
> Deploy the WAR to a Tomcat 7. Then undeploy. In Tomcat manager press "Find
> leaks" button in "Diagnostics" section. Tomcat will complain that after
> undeployment some classes are still in memory.
> Use profiler to locate WebAppClassLoader, see the screenshot.
