Alex created ARTEMIS-5114:
-----------------------------
Summary: deref after NULL
Key: ARTEMIS-5114
URL: https://issues.apache.org/jira/browse/ARTEMIS-5114
Project: ActiveMQ Artemis
Issue Type: Bug
Reporter: Alex
The flushConfirmations() method does not check for connection == null. After
calling the logger, the doWrite() method is called, which uses variables
necessary for checking for null, such as confirmed and connection. If the
confirmed value is checked in replayCommands(), then there is no check for
connection, which will result in a NullPointerException. It is necessary to add
validation either in the doWrite() method itself, or before each use of it.
