RunThese24H.java times out with ParallelGC

The following test failed in the JDK18 CI:

applications/runthese/RunThese24H.java

There are no obvious errors in the log file and here's a snippet
from the end of the log to show timing info:

> result: Error. Program `/opt/mach5/mesos/work_dir/jib-master/install/jdk-18+25-1681/linux-x64.jdk/jdk-18/bin/java' timed out (timeout set to 108000000ms, elapsed time including timeout handling was 108093723ms).

That timeout happened at 108000 seconds => 1800 minutes => 30 hours

We have other open bugs for RunThese time outs. Here's a couple:

JDK-8267571 applications/runthese/RunThese30M.java times out after stress process finishes
JDK-8273107 RunThese24H times out with "java.lang.management.ThreadInfo.getLockName()" is null

but I couldn't really match this failure up with those bugs.
