Description

A static block in org.apache.activemq.util.IntrospectionSupport registers org.apache.activemq.util.StringArrayEditor with java.beans.PropertyEditorManager. In a web application environment, this will cause classloader leaks, since java.beans.PropertyEditorManager keeps a strong reference to the editor class.

ActiveMQ should at least provide a graceful means of deregistering org.apache.activemq.util.StringArrayEditor (by calling java.beans.PropertyEditorManager.registerEditor() again with editor class null).
