Bug in using hashtable-key for removing a known listener

The Code was:
private void removeListener(ChannelID channelID MessageListener
messageListener Connection connection) throws JMSException {
String key = getConsumerKey(channelID messageListener);
MessageConsumer messageConsumer = (MessageConsumer) consumers.get(key);
( ... )
consumers.remove(messageConsumer);
( ... )
}
but should be:
( ... )
consumers.remove(key);
( ... )
has been fixed
