[jira] [Created] (BEAM-10756) TestPubsubSignal provides erroneous messages/out of bounds exception if pull returns empty list

Luke Cwik created BEAM-10756:
--------------------------------

             Summary: TestPubsubSignal provides erroneous messages/out of bounds exception if pull returns empty list
                 Key: BEAM-10756
                 URL: https://issues.apache.org/jira/browse/BEAM-10756
             Project: Beam
          Issue Type: Bug
          Components: io-java-gcp
            Reporter: Luke Cwik
            Assignee: Luke Cwik


TestPubsubSignal assumes that pull() returns null if nothing is returned which isn't the contract of PubsubClient.java, this leads to an ack warning stating that we acked zero messages and an IndexOutOfBoundsException when attempting to get the first resulting message.
