Owen Nichols commented on GEODE-8664: ------------------------------------- Just asking since Affects Version was listed as 1.12 and 1.13 Anyone can propose a backport on the dev list, there is some guidance here: https://cwiki.apache.org/confluence/display/GEODE/Shipping+patch+releases > JGroups exception is not propagated > ----------------------------------- > > Key: GEODE-8664 > URL:
