Octavian Nadolu commented on XERCESJ-1578:
------------------------------------------
I still reproduce the exception.
The locationHint seems to be not correctly expanded. The base system id where
the locationHint is expanded is locationHint. I think the base system id for
the locationHint should be fSchemaGrammarDescription.getBaseSystemId(). Also
the schemaSource systemId is already expanded in the "schemaId" variable. so
you don't need to expand it again, just pass the "schemaId" to the
isValidTargetUriForIncludeOrOverride() method instead of schemaSource.
The example used to reproduce the exception:
main.xsd
--------------------------
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";>
<xs:include schemaLocation="include1.xsd"/>
<xs:override schemaLocation="main.xsd"/>
</xs:schema>
--------------------------
include1.xsd
-----------------------
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";>
<xs:include schemaLocation="include2.xsd"/>
</xs:schema>
-----------------------
include2.xsd
-----------------------
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";>
<xs:override schemaLocation="main.xsd"/>
</xs:schema>
