[jira] [Commented] (VFS-419) JarFileSystem incorrectly resolves
file if it has been removed from the cache
[ https://issues.apache.org/jira/browse/VFS-419?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13287090#comment-13287090 ]
Gary D. Gregory commented on VFS-419:
-------------------------------------
I added
https://svn.apache.org/repos/asf/commons/proper/vfs/trunk/core/src/test/java/org/apache/commons/vfs2/provider/jar/test/JarAttributesTestCase.java
which I thought would show the need for implementing the {{createFile}} method, but the tests pass without it.
So I am still looking for a test that:
# shows the method is required
# shows that the method should do more than just {{return new JarFileObject(name, null, this, false);}}

> If I call fileSystemManager.resolveFile("jar: ... ") and the file was removed from cache, JarFileSystem calls method createFile(AbstractFileName name). This method is not overridden from ZipFileManager and works wrong (its return ZipFileObject instead JarFileObject). But i can override it and make return JarFileObject case this object won't have children and JarURLConnectionImpl won't work. It should reinvalidate cache and return the object with children objects.
> I've added a patch to fix this problem.
