Hi,
Thanks for looking into this. Do note that I have two PRs pertaining to
handling of compressed messages. This one and #5574.
In this case (reported by another user), some handling of a compressed
message can throw a `NegativeArraySizeException` which is demonstrated by the
added test "testUpstreamFederatedAddressWithCompressedMessage". This is a
fairly "straight forward" setup where the federation of a compressed message
triggers the issue. Running that with no other changes will demonstrate the
issue.
While working on a test for this i also stumbled on some similar issue but
that's triggered by a questionable use-case, where sending the same compressed
message multiple times also gives the `NegativeArraySizeException` after a few
sends. The included test "testCompressedMessageRouting" (which is not meant to
be in the final PR) demonstrates the behavior with some added logging and code
comments.
#5574 on the other hand is about consumer credits getting out of balance
when receiving and rollbacking a compressed "regular" message. It will give too
many credits back so the consumerWindowSize will get larger and larger until an
integer overflow happens (leaving the consumer "busy" until restarted).
