David Lloyd created JBTM-2266: --------------------------------- 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). -- This message was sent by Atlassian JIRA (v6.3.1#6329)
