NoClassDefFoundError: com/ibm/mq/server/MQSESSION when running WSMQ adapter in bindings mode

Symptom

GIS 4.1.1 Build Version: 1982_BR4932266_SR1370953
Customer is able to use WSMQ adapter without issue when running in client mode. When switching to bindings mode, an initializer error and no class definition found error is logged in the WebSphereMQSuite.log
Verified that the correct jars are referenced in dynamicclasspath.cfg, and that they exist at the specified locations.
