             Summary: TransactionReaper is using currentTimeMillis for timeout calculation
                 Key: JBTM-2266
                 URL: https://issues.jboss.org/browse/JBTM-2266
             Project: JBoss Transaction Manager
          Issue Type: Bug
    Affects Versions: 5.0.3
            Reporter: David Lloyd
            Assignee: Tom Jenkinson
            Priority: Minor


Noticed while browsing through some code that the TransactionReaper uses currentTimeMillis() to calculate timeouts.  However this method can change if the system time has changed.

An artificial clock based on System.nanoTime() should be used instead, since while this time may vary slightly between cores, in general it will be highly accurate and, most importantly, monotonic and steady (and unaffected by changes to the system time).
