Claus Ibsen commented on AMQ-3797:
----------------------------------

Yeah we hit an issue with AMQ reqistering a javax.jms.Destination property 
editor that played tricks. IMHO property editors in the JDK should not be used, 
as they are per JVM, and you can override each others editors etc.

>             Project: ActiveMQ
>          Issue Type: Bug
>    Affects Versions: 5.4.3
>            Reporter: Mattias Jiderhamn

> 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).
