RFR: 8284779: Test java/util/logging/Logger/logrb/TestLogrbResourceBundle.java fails intermittently with vthreads wrapper [v2]

[Daniel Fuchs]

> Hi,
> 
> Please find enclosed a patch to fix a rare intermittent failure that was detected while testing virtual threads.
> The issue has nothing to do with virtual threads, the test is simply missing a reachability fence to make sure that the parent logger is not garbage collected until its child logger is created.
> 
> best regards,
