Yes it is caused by ProcessServerShutdown.scanMetaRegion() but the
reason it gets reassigned is farther up in the method:

        } else {
          // Get region reassigned
          regions.add(info);

There is no check to see if the region is offline or split.
This is definitely a bug.

The log file snippets helped quite a lot.

Entered Jira HBASE-881.

Thanks Cosmin!
