Description

AbstractFileSystem#checkPath is used to verify that a given path is for the same file system as represented by the AbstractFileSystem instance.

The original intent of the code was to allow for no port to be provided in the checked path, if the default port was being used by the AbstractFileSystem instance. However, before performing port handling, AFS#checkPath compares the full URI authorities for equality. Since the URI authority includes the port, the port handling code is never reached, and thus valid paths may be erroneously considered invalid.
