Given Robert Kanter first filed the patch to do this —why not give him the honour. In fact,
why not have a webex screen share of the occasion so we can all celebrate?

We'll need to be strict after the switch: all patches to go into branch 2 will have to go
through yetus as branch-2 patches, then cherry picked to trunk, or a separate patch on the
same JIRA done for the branch-2. Assuming yetus still tests the branch-2 stuff on JDK7, that
will check version compatibility pre-commit
