Issue/Introduction
javax.jms.JMSException: Connection unknown by server.
Resolution
Beginning with EMS 8.0, a new exception, "javax.jms.JMSException: Connection unknown", is thrown when the EMS server reports, "reconnect failed: connection
unknown for id=xx". The client does not keep trying to reconnect
to the EMS server using the connection object which is no longer held by the EMS server. The connection object could have been purged or deleted administratively.
This new exception was introduced in the following fix in EMS 8.0.0:
EMS-4375: Previously, an EMS client would continue to attempt a connection to an uknown ID. This has been fixed. If a server reports reconnect failed: connection unknown for id=<id>, the client now stops trying to reconnect.

Additional Information
API EMS 8.x and newer both for EMS and client libraries.
