------------------------------------
Summary: Remove unneccessary synchronization in ActiveMQServerImpl
Key: ARTEMIS-2571
URL: https://issues.apache.org/jira/browse/ARTEMIS-2571
Project: ActiveMQ Artemis
Issue Type: Improvement
Components: Broker, Web Console
Affects Versions: 2.10.1
Reporter: Sebastian T
The ActiveMQServerImpl sessions field is a ConcurrentHashMap. Synchronizing on
the ActiveMQServerImpl object to iterate over the map is not necessary.
ActiveMQServerImpl#getSession, ActiveMQServerImpl#removeSession and
ActiveMQServerImpl#createSession also work on the sessions field without
synchronizing on the ActiveMQServerImpl.
Removing the synchronized keyword on the ActiveMQServerImpl#getSessions()
methods e.g. improves loading of Connections view, especially when multiple
administrators are using the UI.
