----------------------------------------------------------------
I'm checking the RabbitMq failure. It seems like initializing
RabbitMq.checkpointMark relies on starting RabbitMq.reader first. Within the
java unbounded wrapper, the calling of checkpointMark::finalizeCheckpoint is
independent from starting the reader. It more seems like the bug inside
RabbitMq. From the
javadoc:https://github.com/apache/beam/blob/master/sdks/java/core/src/main/java/org/apache/beam/sdk/io/UnboundedSource.java#L104-L129,
it's not safe to relay on the reader.
