Ted Yu updated BEAM-2805: ------------------------- Description: {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 was: {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).
