Christian Kadner commented on BAHIR-83:
---------------------------------------
I went back a few more commits to {{a351549}} and rerun the test 100 times with 0 failures.
It looks like before [BAHIR-51: Add new configuration options to MqttStreamSource|https://issues.apache.org/jira/browse/BAHIR-51] this test case run successfully consistently.
