Subject [jira] [Commented] (AXIS2-4072) URLClassloader locking jarfiles on Windows
Date Sat, 02 Jul 2016 13:35:11 GMT

    [ https://issues.apache.org/jira/browse/AXIS2-4072?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15360174#comment-15360174

Hudson commented on AXIS2-4072:
-------------------------------

SUCCESS: Integrated in Axis2 #3571 (See [https://builds.apache.org/job/Axis2/3571/])
AXIS2-5792: Use the same class loaders on Windows as on Unix, to make EnableChildFirstClassLoading
work (AXIS2-4349 only implementd that feature for Unix). This effectively reverts the change
implemented in AXIS2-4072 and instead levarages the fact that on recent Java versions, URLClassLoader
has a close() method. (veithen: rev 1751057)

>          Issue Type: Bug
>    Affects Versions: 1.4.1
>         Environment: Windows XP, Geronimo 2.1.3
>            Reporter: Tim McConnell
>            Assignee: Jarek Gawor

> There is at least one scenario using Axis2 and Geronimo that is causing jarfiles to get
locked on Windows such that a deployed WAR cannot be either redeployed or uninstalled. Here
is a brief description of the failing scenario:
> 1. A WAR file containing various jarfiles in the /lib directory is deployed on Geronimo
2.1.3
> 2. Navigate to the deployed app's address to generate the WSDL for the web service
> 3. Redeploy or uninstall of the WAR will now fail since all the jarfiles in the WAR /lib
directory are locked by Windows and cannot be deleted.
> What appears to be happening is that there are three Axis2 URLClassLoaders in this scenario
and at least two of them are creating their own ClassPath and URLClassPath$JarLoader objects
that apparently are locking the jarfiles in the /lib directory.
