-----------------------------
Summary: deref after NULL in ChannelImpl.java
Key: ARTEMIS-5115
URL: https://issues.apache.org/jira/browse/ARTEMIS-5115
Project: ActiveMQ Artemis
Issue Type: Bug
Reporter: Alex
In the clearUpTo method, packages are cleared one at a time to the specified
command ID. If the logger is enabled, information about RemotingConnectionID,
lastReceived commandId and other data is displayed. In the first if
construction, the correct ternary operator is written, which checks the value
of connection == null
Below in the loop is [another if
construction|[https://github.com/apache/activemq-artemis/blob/4c6cded2e79cf10d2323de1b5fa7418b289ab034/artemis-core-client/src/main/java/org/apache/activemq/artemis/core/protocol/core/impl/ChannelImpl.java#L874-L875]],
where there is no connection check for null, which can lead to a
NullPointerException program error.
