David Hotham commented on JGRP-1461:
------------------------------------

Yes, the same thought occurred to me. 

However, I was reluctant to make bigger changes than necessary.  As with so much in JGroups, my head starts hurting when I try to think of window conditions that might break things; so I figured that the sensible thing to do was to make the smallest change I could!

> As noted in JGRP-1458, it looks as though SEQUENCER always thinks that sequence numbers must start at zero.  But a member who joins a group after some messages have already been broadcast may never receive sequence number zero.  So, I think, his SeqnoTable will grow indefinitely.
> Note that this one's mostly through code reading.  I think I'm right; but I'm happy to be told otherwise!
> Pull request to follow shortly.
