     * Returns the JAR file.  May be null if the jar is remote.

     * If the JAR file is cached in the JAR cache, returns true and
     * holds a reference to the cached zip reader to be used when
     * the channel is read from, ensuring the cached reader will be used.
     * For a successful read from the cached reader, close() should not
     * be called on the reader--per nsIZipReader::getZip() documentation.
     * Returns false if the JAR file is not cached. Calling this method
     * after the channel has been opened is not permitted.
