        Same here, these tests time out and fail frequently for me.

        I encountered the same symptoms (test seems to complete successfully but the client thread does not return) with 3 JUnit tests: TestBroadcastExchange, TestHashToRandomExchange and TestOrderedPartitionExchange. There's no error in the Lilith log. These tests time out for me. I have all the latest changes from the upstream master branch.
