Warn message in ActiveMQ Artemis console
I'm using ActiveMQ Artemis 2.28.0, and I suddenly received this warning message:
2023-09-19 09:49:09,160 WARN [org.eclipse.jetty.server.HttpChannel] /console/jolokia/
java.lang.IllegalStateException: null
Solution
The WARN message is being logged by Jetty (i.e. the embedded web server) which is not part of the ActiveMQ Artemis code-base. Looking at the relevant source code from Jetty indicates that the exception is due to an attempt to invalidate a web session that is already invalid. There should be no functional impact here.
