Octavian Nadolu commented on XERCESJ-1578:
------------------------------------------
The fix is not so good. When you compare the system ids of the files you should
use "equal" method instead of "==". Also make sure that the both system ids are
expanded when you compare them.
Anyway, the problem can be reproduced if I validate the main.xsd file from the
following sample:
main.xsd
--------------------------
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";>
<xs:include schemaLocation="include.xsd"/>
</xs:schema>
--------------------------
include.xsd
-----------------------
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";>
<xs:include schemaLocation="main.xsd"/>
<xs:override schemaLocation="main.xsd"/>
</xs:schema>
