             Summary: Remove WindowedValue#valueInEmptyWindows
                 Key: BEAM-230
                 URL: https://issues.apache.org/jira/browse/BEAM-230
             Project: Beam
          Issue Type: Bug
          Components: sdk-java-core
            Reporter: Thomas Groh
            Assignee: Davor Bonaci


A WindowedValue in no windows does not exist, and can be dropped by a runner at any time.

We should also assert that any collection of windows is nonempty when creating a new WindowedValue.
If a user wants to drop an element, they should explicitly filter it out rather than expecting
it to be dropped by the runner.
