Ken Wills commented on WFCORE-3103:
-----------------------------------

[~jbliznak] I've been looking at this on Windows 10. It appears that the reproducer doesn't find any handles from just running with wildfly-core (master). Am I misunderstanding the reproducer, that it should have test failures, or should they all pass?

> When embedded server is started programatically (eg. via CLI wrapper) with specified jboss home, JARs from that path are opened via classloader. But these open handles are never released even after embedded server is stopped. 
> This causes problem in situation eg. when you want to delete that jboss home. This is exactly one of the scenarios used in EAP installer, you are not allowed to delete open files on Windows - see JBEAP-1404.
> I created a simple project that reproduce the issue with arbitrary EAP/WF distribution https://github.com/jbliznak/embedded-server-filelocking
> Run it with:
> mvn clean test "-Dwildfly.home=C:\dev\jboss-eap-7.1" "-Denforcer.skip" -Dtest=ModulesFileLockingTestCase
> Manual steps to reproduce in Java code:
> * start a CLI wrapper
> * start embed-server from given server path
> * stop embed-server
> * terminate CLI wrapper
> * try to delete given server path
