[BUG] MX bean missing: G1 Concurrent GC error message

[f-galland]

Describe the bug

Hi Team,

After a clean install of OpenSearch 2.15, I can observe the following error in /var/log/opensearch/opensearch.log:

[2024-07-25T12:36:54,732][ERROR][o.o.p.c.j.GCMetrics      ] [ubuntu] MX bean missing: G1 Concurrent GC

This doesn't seem to cause any observable issues, but I would still like to report it and get your comments on the subject.

Is there anything I can do to fix this error?

We are keeping track of this problem in an issue in our own repo as well.

Let me know if you need any further information.

@f-galland Thank for creating this issue, can you indicate how you installed OpenSearch otherwise we are assuming that this is Java Runtime 21.
