---------------------------------------
Summary: Memory leak while shutting down the tomcat server with embedded JMS server
Key: ARTEMIS-1014
URL: https://issues.apache.org/jira/browse/ARTEMIS-1014
Project: ActiveMQ Artemis
Issue Type: Bug
Affects Versions: 1.5.3
Environment: Tomcat 9
Java 8
Reporter: Vishal Agarwal
I am using Artemis server as an embedded server in my webapp.
The Embedded server is started as spring-bean as explained in the Spring Integration examples provided by Artemis.
When tomcat server is shut down following warning comes in console:

INFO: A valid shutdown command was received via the shutdown port. Stopping the Server instance.

Threads are going to be renewed over time to try and avoid a probable memory leak.
