A similar failure with this test was previously addressed via:

CODETOOLS-7903538 NullPointerException: Cannot read the array length because "<local9>" is null

According to the task's stdout log, the JTREG version is:

[2024-08-06T12:28:33,974Z] [jib LOG] JT_HOME=/cygdrive/c/ade/mesos/work_dir/jib-master/install/jtreg/7.4/1/bundles/jtreg-7.4+1.zip/jtreg

CODETOOLS-7903538 is fixed in jtreg-7.4. Please note
that I can't set the "Affects Version/s" value to "7.4".
