Hy everyone, I use the plugin cargo-maven2-plugin to run my integration test on tomcat 8 (waiting the tomcat8-maven-plugin)
Unfortunetly, I've this stack when I stop the container:
The web application [sportInfo] appears to have started a thread named [transcoder-2-1] but has failed to stop it. This is very likely to create a memory leak. Stack trace of thread:
And
java.lang.ref.WeakReference@606a2c5b}]) but failed to remove it when the web application was stopped. Threads are going to be renewed over time to try and avoid a probable memory leak.
The full Stack:

Can you help me please?
Why you execute start goal twice? It is in pre integraton phase and then durign exceution. Maybe this is your problem? I mean that you are running it twice in two threads. And why is run execution configuration empty?
