[jira] [Created] (ARTEMIS-1058) Jars in web tmp dir locked on Windows

Howard Gao created ARTEMIS-1058:
-----------------------------------

             Summary: 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.
