-----------------------------------
Summary: Classloader memory leak by Threads which is started by
org.apache.openejb.loader.Files
Key: OPENEJB-1961
URL: https://issues.apache.org/jira/browse/OPENEJB-1961
Project: OpenEJB
Issue Type: Bug
Components: tomee
Reporter: chunlinyao
Priority: Minor
org.apache.openejb.loader.Files registered ShutdownHook, which will create a
Thread.
When new a Thread, the thread will record contextClassLoader and
inheritedAccessControlContext,
If Files is first called by a Thread using LazyStopWebappClassLoader, it will
hold the classLoader.
Daemon Thread [localhost-startStop-1] (Class load: Files)
owns: StandardContext (id=262)

We must load Files from other thread first to prevent this leak.
