clebert suconic commented on ARTEMIS-2185:
------------------------------------------
I don't think this is an issue. this is generating failures.. not the usual
case... I don't see a reason to optimize the failure case here.
I think this is a non issue.
> High allocation pressure due to pre generated ActiveMQExceptionMessage

> Key: ARTEMIS-2185
> URL: https://issues.apache.org/jira/browse/ARTEMIS-2185
> Project: ActiveMQ Artemis
> Issue Type: Improvement
> Components: Broker
> Affects Versions: 2.6.3
> Reporter: juergen schmied
> Priority: Minor
> Labels: ChannelImpl, Memory, collection, garbage
> Attachments: tempsnip.png
>
>
> In org.apache.activemq.artemis.core.protocol.core.impl.ChannelImpl there is
> {code:java}
> public void returnBlocking(Throwable cause) {
> lock.lock();
> try {
> response = new
> ActiveMQExceptionMessage(ActiveMQClientMessageBundle.BUNDLE.unblockingACall(cause));
> sendCondition.signal();
> } finally {
> lock.unlock();
> }
> }
> {code}
> The response is created but not used normally.
> For every get/close connection there is the a ActiveMQExceptionMessage incl.
> stacktrace created and abandoned.
> This shows a high allocation pressure in jmc (8 MB garbage/200 calls).
> please don't precreate the unused exception (maybe use a producer producing
> exception when really needed)
