   * A InitialContextFactory for WebSphere Generic JMS Provider.

   * property defined for Generic JMS Provider are passed to {@link InitialContextFactory}
   * only if it begins with {@code java.naming} or {@code javax.naming} prefix.
   * Additionally provider url for the JMS provider can not contain {@code ','}

   * of this class is to transform properties before passing it to
