Work Description: kennknowles commented on issue #6305: [BEAM-5265] Use
currentProcessingTime() for onTime with processing time domain
URL: https://github.com/apache/beam/pull/6305#issuecomment-433058029
The processing time can be arbitrarily far ahead of the watermark, or behind
it. They are independent, even though in a lot of streaming applications they
will be near each other.
So if the watermark is behind processing time, you'll get timestamps that
are outside the window and that is forbidden. If the watermark is ahead of
processing time (more rare and weird probably, since you would be processing
future events) then you get dropping.

> I have a stateful DoFn which has a timer on PROCESSING_TIME domain. While
> writing tests, I noticed that it does not react to `advanceProcessingTime()`
> on tests stream. Problem seems to be here:
> [https://github.com/apache/beam/blob/master/runners/core-java/src/main/java/org/apache/beam/runners/core/SimpleDoFnRunner.java#L260]
> I can only tell that patching this place works for direct runner tests. Not
> sure about broader impact on other runners since it is in `runner-core`
