16:55:37 TEST RESULT: Error. Program `/home/jenkins/workspace/Test_openjdk8_j9_extended.openjdk_ppc64_aix/openjdkbinary/j2sdk-image/bin/java' timed out (timeout set to 80000ms, elapsed time including timeout handling was 82329ms).
```

Start with the linked console output and jdk/test/sun/security/krb5/auto/Unreachable.java, using the provided rerun command to reproduce the timeout on AIX. Trace the Kerberos test's wait at the reported stack frames and verify that the test completes within its timeout on both HotSpot and OpenJ9.
