@clebertsuconic I don't think this is the case. All files except Jar files
in web-inf/lib can be deleted automatically. This is because the classloader
didn't release the inputstream on Jar files, it relies on GC to close the
streams, which you never be sure when to happen.
> Jars in web tmp dir locked on Windows

> Key: ARTEMIS-1058
> URL: https://issues.apache.org/jira/browse/ARTEMIS-1058
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Components: Broker
> Affects Versions: 1.5.3
> Environment: Windows
> Reporter: Howard Gao
> Assignee: Howard Gao
> Priority: Minor
> Fix For: 2.0.0
>
>
> The embedded jetty web server's WebAppClassloader holds up webapp's jar files
> and does not release them after close. For that reason the web app's temp dir
> cannot be cleaned up on Windows. (Other platforms like Linux doesn't prevent
> a force delete of files even they are not released).
> As long as this behavior exists we need to have a workaround to let
> the tmp dir be cleaned up.
> It is possible that we use a 'customized' classloader to replace jetty's
> WebAppClassloader, in which we manually iterate every JarFile resources
> and close them.
