Work Description: tweise commented on pull request #7530: [BEAM-6440] Fix
leakage of timer de-duplication map
URL: https://github.com/apache/beam/pull/7530
The FlinkStateInternals use a keyed map of pending timers to make up for
Flink's
limitation to only be able to delete timers with their original timestamp,
not
via timer id.
The Map leaked memory because subclasses of DoFnOperator overwrote
`fireTimer`
which was responsible for performing cleanup in the map upon firing a timer.
