[jira] [Updated] (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:all-tabpanel ]
Sergey Grigorev updated VFS-419:
--------------------------------
Description:
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.
