Ted Yu created BEAM-2805:
----------------------------

             Summary: Potential arithmetic overflow in Generator#nextAuctionLengthMs()
                 Key: BEAM-2805
                 URL: https://issues.apache.org/jira/browse/BEAM-2805
             Project: Beam
          Issue Type: Bug
          Components: sdk-java-extensions
            Reporter: Ted Yu
            Assignee: Reuven Lax
            Priority: Minor


{code}
    long numEventsForAuctions =
        (config.configuration.numInFlightAuctions * GeneratorConfig.PROPORTION_DENOMINATOR)
        / GeneratorConfig.AUCTION_PROPORTION;
{code}
The multiplication is done on 32-bit integers while long is expected (numEventsForAuctions).

There is possibility for arithmetic overflow
