Is there any particular reason why rejectMessage() still calls messageRelease()
? Should I file bug report? This is from QPID 0.18.
Thanks, Jan
/**
* Release (0_8 notion of Reject) an acquired message
*
* @param deliveryTag the message ID
* @param requeue always true
*/
public void rejectMessage(long deliveryTag, boolean requeue)
{
// The value of requeue is always true
RangeSet ranges = RangeSetFactory.createRangeSet();
ranges.add((int) deliveryTag);
flushProcessed(ranges, false);
if (requeue)
{
getQpidSession().messageRelease(ranges);
}
else
{
getQpidSession().messageRelease(ranges, Option.SET_REDELIVERED);
}
//I don't think we need to sync
}
