Description

Hello ,
I was using Plumbr (https://plumbr.eu/) to test our application for memory Leaks.
The plumr tool showed me that we have a memory leak when we need to redeploy our application.

I would like to mention that we keep all of the Trinidad depedencies in <tomcat_dir>/lib folder (Shared classloader for all webapps)

Here is the memory leak text.

The leaking classloader is being held
in key of java.util.HashMap$Entry
in table of java.util.HashMap
in static _CONFIGURATORS of org.apache.myfaces.trinidadinternal.config.GlobalConfiguratorImpl
in elementData of java.util.Vector
in classes of org.apache.catalina.loader.StandardClassLoader
in org.apache.tomcat.util.net.SocketWrapper
in reference from native code (JNI local)
