> This is a race, I have been unable to reproduce in an isolated test, but it
> is trivial to reproduce in a google internal integration suite with the
> following change to
> runners/direct-java/src/main/java/org/apache/beam/runners/direct/ExecutorServiceParallelExecutor.java
> {code}
> // Get an update; don't block forever if another thread has handled
> it. The call to poll will
> // wait the entire timeout; this call primarily exists to relinquish
> any core.
> VisibleExecutorUpdate update =
> visibleUpdates.tryNext(Duration.millis(25L));
> + Thread.sleep(100);
>
> if (update == null && pipelineState.get().isTerminal()) {
> {code}
