Since this test stresses the system dictionary, I'm starting
this bug in hotspot/runtime for initial triage.

Ok.. The description is back. I had to remove all . in java.lang ... Now I can save it. Don't ask me why.

Sorry for meddling with the description here, but there's a character in the original description that can't be saved, preventing certain updates to the bug.

The test log from 1-Jan-2021 shows a lot of these messages. Could that have helped cause the test failure?
