Francesco Nigro updated ARTEMIS-3618:
-------------------------------------

SecurityManager (was: Artemis CORE client can skip a secured action on
MessageListener's hot path)
> Faster Artemis CORE client MessageListener::onMessage without SecurityManager
> -----------------------------------------------------------------------------
>
> Key: ARTEMIS-3618
> URL: https://issues.apache.org/jira/browse/ARTEMIS-3618
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Reporter: Francesco Nigro
> Assignee: Francesco Nigro
> Priority: Major
>
> Currently {{ClientConsumerImpl}}, responsible of calling JMS
> {{MessageListener::onMessage}}, is installing/restoring the listener thread's
> context ClassLoader by using a secured action regardless any security manager
> is installed.
> This secured action (using {{AccessController::doPrivileged}}) is very
> heavyweight and can often be as costy as the user/application code handling
> the received message (see https://bugs.openjdk.java.net/browse/JDK-8062162
> for more info)
