===============================================
tools/jlink/basic/AllModulePath.java
Total tests run: 3, Passes: 3, Failures: 0, Skips: 0
===============================================

result: Error. Agent error: java.lang.Exception: Agent 12 timed out with a timeout of 480 seconds; check console log for any additional details

Default timeout value of 120 seconds/2 minutes with a default timeoutFactor
of 4 means a total timeout of 480 seconds/8 minutes. The run executed
for 685.36 seconds. The test did manage to pass while the timeout handler
was running.


Unlike most tests where we've run into timeouts, this test includes
timestamps in its logging output so we can see that the test really
does take quite a bit of time for its various steps.
