    Description

      Load testing our application (the JIRA Issue Tracker) has shown that threads spend a lot of time blocked in DateTools.stringToDate().

      The stringToDate() method uses a singleton SimpleDateFormat object to parse the dates.
      Each call to SimpleDateFormat.parse() is synchronized because SimpleDateFormat is not thread safe.
