----------------------------------------
Summary: NPE thrown by NettyConnector::createConnection
Key: ARTEMIS-2093
URL: https://issues.apache.org/jira/browse/ARTEMIS-2093
Project: ActiveMQ Artemis
Issue Type: Bug
Components: Broker
Affects Versions: 2.6.3
Reporter: Francesco Nigro
Assignee: Francesco Nigro
Fix For: 2.7.0, 2.6.4
On NettyConnector::createConnection,
ChannelPipeline::get(ActiveMQChannelHandler.class) can return null, causing
NPE, if the channel is being closed and/or the channel pipeline is being
cleaned up before it.
It can happen because NettyConnector::createConnection is not being called
inside the channel's event loop and is concurrent with a channel close event
(that's completed into the event loop).
