Symptom
During the Managed System Configuration of a Java technical system, the Java logon test via button "Test Logon..." in the Java Parameters pane fails with the following error:
| A technical error occured; Java credentials could not be checked Error Action failed : An error occured while communicating with Message Server <host.domain>:<internal message server port> through the instance <host>/<SID>/<instance number> (<host>) : Error to retrieve the process from Message Server (detail: java.io.IOException: Cannot connect to message server. Make sure that you connect to the message server using the internal port and/or check whether the access control file is up-to-date.); nested exception is: java.io.IOException: Cannot connect to message server. Make sure that you connect to the message server using the internal port and/or check whether the access control file is up-to-date.(cause=java.io.IOException Cannot connect to message server. Make sure that you connect to the message server using the internal port and/or check whether the access control file is up-to-date.). Therefore the preliminary look-up of the Managed Java Message Server information (<host.domain>:<internal message server port>) via the Agent is not possible. |
More details can be found in the SMDAgentApplication*.log file:

Additionally, in the dev_ms of the Java stack, errors like the following are logged:
