There was hit a regression (against 8.0.0.Beta) in one of the messaging scenarios with Undertow loadbalancer:

Start EAP configured as a static load balancer using reverse proxy
Start 2 EAP backend servers with messaging
Producer starts to send messages, it uses connection factory pointing to loadbalancer, not knowing about backed workers
Producer repeats sending with creating of new connection - connections should be balanced between workers
Receiver receives messages, it uses connection factory pointing to loadbalancer, not knowing about backed workers
Receiver repeats receive with creating of new connection - connections should be balanced between workers and receive messages from all of them

Expected result: Receiver gets the same amount of messages as was sent
Actual result: None of the clients is connected

By bisecting the commits it seems that regression is caused by:
https://github.com/undertow-io/undertow/commit/ffccfee47114828d9516afbd44fb99565d3d0f78

There is error on server with load-balancer:
