027 * This implementation of <CODE>InitialContextFactory</CODE> should be used when ActiveMQ is used as WebSphere Generic JMS Provider.

029 * are passed to InitialContextFactory only if it begins with java.naming or javax.naming prefix.
030 * Additionaly provider url for the JMS provider can not contain ',' character that is necessary when the list of nodes is provided.
031 * So the role of this class is to transform properties before passing it to <CODE>ActiveMQInitialContextFactory</CODE>.
