[jira] Resolved: (AXIS2-4282) JarFileClassLoader allows resources to be loaded from locations outside of the directory specified in its classpath

Andreas Veithen resolved AXIS2-4282.
------------------------------------

    Resolution: Fixed

Checked that the behavior is compatible with URLClassLoader and added a unit test. Note that URLClassLoader doesn't seem to adhere strictly to the rules in [1] which forbid ".." altogether. URLClassLoader allows ".." in resource names as long as the resource name doesn't specify a file outside of the directory (e.g. "META-INF/../someother.file"). So no need to further restrict allowable resource names.

> If JarFileClassLoader contains one classpath entry that is a directory, it will allow resources to be loaded from ANY directory on the file system.
> The JarFileClassLoader should of course only allow resources to be loaded from within the directory specified.
