After uprade to 8.1.1.11/8.2.2.4+ do not forget to enable MT-option for JMSReceiver component
Just t for your information:
The Note 1608961.1 , outlines steps one need to perform manually to define a custom JMS Receiver component that would operate as MT Server component.
In the new installation the JMS Receiver is already enabled by this new (to EAI Receiver architecture) option,
however for an upgraded Siebel CRM Enterprise this feature needs to be enabled manually.
Thanks,
Alexey
