Subject [jira] [Resolved] (AMQ-3797) org.apache.activemq.util.StringArrayEditor causes classloader leaks

Claus Ibsen resolved AMQ-3797.
------------------------------

       Resolution: Fixed
    Fix Version/s: 5.7.0
         Assignee: Claus Ibsen

Okay I have refactored the code to not use StringArrayEditor as a JDK property editor, and
thus we dont enlist it to the property editor manager. Which then should fix the leak.

> 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).
