Hi all,

could you please review this trivial patch which removes @ignore from LFGarbageCollectedTest and adds it into problem-list instead?

from  8249698:
> java/lang/invoke/LFCaching/LFGarbageCollectedTest.java is excluded from execution due to JDK-8078602. although the test might indeed fail due to JDK-8078602, it still can be useful and isn't harmful to run, therefore this test should be put in ProblemList.txt and @ignore is to be removed.
from main issue(8249618):
> although ProblemList and @ignore achieve the same end result (test exclusion), their server different goals and have slightly different meanings, simplified @ignore should be used to exclude useless or harmful tests, and ProblemList in all other cases (see yet-not-integrated `ProblemListing or `@ignore`-ing a Test` section of dev guide, PR -- https://github.com/openjdk/guide/pull/21 for more details). 
> 
> due to different reasons, this hasn't been always followed and some currently @ignore-d tests should rather be ProblemList-ed, and some of ProblemList-ed should be @ignore-d, this issue is to clean up the current state in a hope that this will reduce further confusion.
