JavaTest Message: Test complete.

result: Error. "driver" action timed out with a timeout of 120 seconds on agent 9


Based on the start time:
    start=Tue Oct 14 09\:15\:46 UTC 2025

and the time stamp on the last command:
    [2025-10-14T09:17:50.614807700Z] Waiting for completion finished for process 9208

the test really did execute for > 2:04 which is 124 seconds
and that was to the start of the last command execution.

The timeout did not reproduce in the next five Tier2 job sets
so I've added the 'intermittent' label and I'm starting this issue
off as a P4.
