Subject [GitHub] incubator-beam pull request #450: [flink] fix potential NPE in ParDoWrapper

    [flink] fix potential NPE in ParDoWrapper

    Just discovered this while checking for correct execution of the bundle life cycle. This
fixes potential NPEs in the ParDo translation wrapper. `startBundle(context)` receives `null`
as `context` before the first element has been read. Similarly, `finishBundle(context)` receives
`null` as `context` if no elements have been read.
