[jira] Updated: (VFS-82) ClassCastException in AbstractFileObject
when using OnCall caching
[ http://issues.apache.org/jira/browse/VFS-82?page=all ]
Ethan Killian updated VFS-82:
-----------------------------
Attachment: AbstractFileObject.patch
Fix for ClassCastException problem. Since the files that are resolved may not be AbstractFileObject's cannot just call deleteSelf() which is only an AbstractFileObject method. Instead check if it is indeed an AbstractFileObject and call deleteSelf(), otherwise use the FileObject interface to delete a single file.

>
> When using OnCall caching in the file system, there is a ClassCastException in the AbstractFileObject because it assumes that every child it will encounter will also be an AbstractFileObject as well.
> Here is the stack trace in question:
> Exception in thread "AWT-EventQueue-0" java.lang.ClassCastException: org.apache.commons.vfs.cache.OnCallRefreshFileObject
> at org.apache.commons.vfs.provider.AbstractFileObject.delete(AbstractFileObject.java:748)
> at org.apache.commons.vfs.impl.DecoratedFileObject.delete(DecoratedFileObject.java:79)
> at org.apache.commons.vfs.cache.OnCallRefreshFileObject.delete(OnCallRefreshFileObject.java:74)
