Subject: jmx-dev JMX Group dissolved.  Merged into Serviceability.
Message-ID: <DM3PPF1D4534BE49163C136CCDFE9371EA2976DA@DM3PPF1D4534BE4.namprd10.prod.outlook.com>

Confidential - Oracle Restricted \Including External Recipients

Hi jmx-dev,

The JMX group is being dissolved, see recent governing board vote [0].

The group is effectively a subset of the serviceability group, so all concerns are being merged into that group.

The jmx-dev at openjdk.org mailing list will be removed.  Please use serviceability-dev at openjdk.org instead.  Rules for PRs based on filenames will be updated, so very little action should be required.

Thanks
Kevin

It seems it would be better to split this large patch into smaller parts. I?ll do that.
