------------------------------------
Summary: PubsubIO fails with NPE on ACK when running locally
Key: BEAM-1977
URL: https://issues.apache.org/jira/browse/BEAM-1977
Project: Beam
Issue Type: Bug
Components: sdk-java-core
Affects Versions: 0.6.0
Reporter: Keith Berkoben
Assignee: Davor Bonaci
When running a PubsubIO-fed pipeline on a local machine, the pipeline runs for
10sec and then fails with a NPE (I'd guess when trying to ACK messages?).
Logs confirm I am successfully reading messages and writing them out to
pubsubIO, at least for a while.
