webmethods MQ Adapter 6.5 and the property watt.MQSeries.Sup

The property watt.MQSeries.Suppress.JMSType.tag doesn’t seem to be working with the adapter version 6.5.

When we send a MQRFH2 message to a JMS Client, we still have the header. The client is unable to process the message because of this tag.

Is there another way to suppress the tag ?
