Subject [jira] Commented: (AMQCPP-186) CMSExpiration computed incorrectly (?)
Date Tue, 01 Jul 2008 12:16:00 GMT

    [ https://issues.apache.org/activemq/browse/AMQCPP-186?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=43819#action_43819
] 

Timothy Bish commented on AMQCPP-186:
-------------------------------------

If you could provide C++ and Java sample code to reproduce the problem that would be helpful.
 The C++ isExpired code looks like this:

{noformat} 

        virtual bool isExpired() const {
            long long expireTime = this->getCMSExpiration();
            long long currentTime = decaf::util::Date::getCurrentTimeMilliseconds();
            if( expireTime > 0 && currentTime > expireTime ) {
                return true;
            }
            return false;
        }

{noformat} 

And the Java code

{noformat} 

    public boolean isExpired() {
        long expireTime = this.getExpiration();
        if (expireTime > 0 && System.currentTimeMillis() > expireTime) {
            return true;
        }
        return false;
    }

{noformat}

> The C++ consumer is treating messages as expired in situations where the Java consumer
is not.
> It could be that the problem is due to the code in connector/openwire/commands/ActiveMQMessageBase.h
which compares the CMSExpiration time specified by producer.setTimeToLive()  with the local
clock on the consumer machine.
