> The change for "ARTEMIS-3474 replace non-inclusive terms" in 2.32.0 changed a String that was used on the wire for Voting. That string was sent on the Vote packet, and so created an incompatibility if mixing a broker <= 2.31.2 with those of versions 2.32.0 - 2.36.0 (e.g during a rolling upgrade) where they dont understand each others values. The other nodes would fail with the following message:
> AMQ224090: This node is not configured for Quorum Voting, all nodes must be configured for HA
> The server will simply not respond the VoteRequest on that case and the blockCall timeout will fail.
> To fix this I'm applying a shorter timeout that will just be ignored and retry with the older packet in case the response wasn't found, before trying for the full timeout with the current value.
> The wire version will be bumped in 2.37.0 such that this process does not occur against new brokers, which will then be known to understand both values.
