Improve performance related to TimerServiceImpl#scheduledTimerFutures

    XMLWordPrintable

Details

    Description

      org.jboss.as.ejb3.timerservice.TimerServiceImpl#scheduledTimerFutures maintains a HashMap of timer id to TimerTask. Currently all access to it is wrapped in synchronized block. Need to investigate if we can optimize the locking to improve response time.
