[jira] [Updated] (ARTEMIS-3618) Artemis CORE client can skip a secured action on MessageListener's hot path
[ https://issues.apache.org/jira/browse/ARTEMIS-3618?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Francesco Nigro updated ARTEMIS-3618:
-------------------------------------
Description:
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)
