[jira] [Updated] (BEAM-2805) Potential arithmetic overflow in
Generator#nextAuctionLengthMs()
[ https://issues.apache.org/jira/browse/BEAM-2805?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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
