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