Nick Dimiduk updated HBASE-26906:
---------------------------------
Affects Version/s: 2.5.0
Hmm. This affects branch-2 and branch-2.5 only. Looking at the blame on 2.5, I
don't see a strong reason for one version or the other. It looks like the
dependency was introduced via HBASE-26691 and includes the extra exclusion. The
second declaration came without the exclusion via HBASE-26802. Before these
changes, there was no explicit mention of this dependency.
