Last updated on JULY 06, 2020

Applies to:

Oracle GlassFish Server - Version 2.1 and later
Information in this document applies to any platform.

Symptoms

The Message Queue (MQ)  broker process (imqbrokerd) does not start up.  Specifically, if the MQ broker was started at the terminal console, you would see the following exceptions:

Now, there are situations where MQ brokers are started through startup scripts or started by the GlassFish Enterprise Server as it message queue broker.  In those cases, the full error message is not logged, and there is little in the broker's log file to indicate what the problem is.  For example, this is what you can see in the log file located in the MQ broker instance's log directory (IMQ_VARHOME/instances/<brokername>/log/log.txt:


The log file will show that the last line for the process before it stops to be "[B1239]: Using platform MBean server".
