> 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)
