Clebert Suconic commented on ARTEMIS-3665:
------------------------------------------
I had a De Ja Voux that I had fixed a similar issue around topology updates...
I even thought this was ARTEMIS-2868... However the commit for it is already
included in 2.17.0
Then I was going to check on ARTEMIS-3337... which I believe it could be
related to your issue.
Anyway... it seems this is fixed on 2.20.0 and perhaps 2.19.1 (2.19.1 still has
the finalize calls, so 2.20.0 is more recommended for you).
We should have 2.21.0 coming out in a few weeks also.
