[Jenkins job xlinux](https://hyc-runtimes-jenkins.swg-devops.com/job/Test_openjdk8_ibm_extended.jck_x86-32_linux/23/consoleFull)

The issue is intermittent. Reran in [Grinder](https://hyc-runtimes-jenkins.swg-devops.com/job/Grinder/51353/console) seems fine.

```

Start in TestDivider.java at parseDuration (line 167) and getDataFromTRSS (line 257), then review the createDurationQueue flow. Compare the failing Jenkins logs with the successful Grinder run and inspect the TRSS response handling. Done means intermittent getTestAvgDuration responses no longer leave TKG without test duration data.
