Looks like running the test in -Xcomp and also with jtreg creates
pressure to the young gen and more object allocation failure and so
unreachable objects get collected in the middle of a small method body
(like in this case).
You added code to reference the local variables referencing the
loggers. Would it be simpler to have this test just to hold a strong
reference to the logger?
