028     * when ActiveMQ is used as WebSphere Generic JMS Provider. It is proved that it
029     * works on WebSphere 5.1. The reason for using this class is that custom
030     * property defined for Generic JMS Provider are passed to InitialContextFactory
031     * only if it begins with java.naming or javax.naming prefix. Additionaly
032     * provider url for the JMS provider can not contain ',' character that is
033     * necessary when the list of nodes is provided. So the role of this class is to
034     * transform properties before passing it to
035     * <CODE>ActiveMQInitialContextFactory</CODE>.
