RFR: 8372242: Gtest LogTagSet.defaults should run in OTHER VM

Thu Nov 20 09:13:25 UTC 2025

LogTagSet.defaults checks some of the default `LogTagSet` properties and assumes a fresh VM. This test will fail if the other `LogTagSet` have run first.

As this test is ment to test the defaults of the LogTagSet, it should be ran in an OTHER VM. 

We might still have problems if logging flags are given to the GTestLauncher. But all our jtreg GTest runners are `@requires vm.flagless`, so this should only occur when running very custom test invocations.
