Description

When trying to extract an XPI file (Firefox extenstion, which probably is not a best candidate for extract) I got the below exception.
It was caused by SYSTEM entities refering the chrome:// protocol.
However, obviously any XML file that contains SYSTEM entities which can not be accessed at the time of extraction will not be extracted properly.

Here is the stack trace:
