[jira] Created: (XERCESJ-1500) ArrayIndexOutOfBoundsException in
SchemaGrammar
ArrayIndexOutOfBoundsException in SchemaGrammar
-----------------------------------------------
Key: XERCESJ-1500
URL: https://issues.apache.org/jira/browse/XERCESJ-1500
Project: Xerces2-J
Issue Type: Bug
Components: XML Schema API
Affects Versions: 2.11.0
Reporter: Vojtěch Toman
I got an ArrayIndexOutOfBoundsException in the SchemaGrammar(SchemaGrammar constructor):
...
// Groups being redefined by restriction
fRGCount = grammar.fRGCount;
if (fRGCount > 0) {
fRedefinedGroupDecls = new XSGroupDecl[grammar.fRedefinedGroupDecls.length];
fRGLocators = new SimpleLocator[grammar.fRGLocators.length];
System.arraycopy(grammar.fRedefinedGroupDecls, 0, fRedefinedGroupDecls, 0, fRGCount);
// HERE
System.arraycopy(grammar.fRGLocators, 0, fRGLocators, 0, fRGCount);
}
...
The reason for the exception was that the size of both grammar.fRGLocators and fRGLocators was 2, but the value of fRGCount was 4.
It is relatively difficult do describe my setup, but I am basically doing the following:
- Validating a sequence of DITA documents using the same DOMParser instance
- The parser is using a custom grammar pool implementation
It all worked fine with Xerces 2.9.1, but not with Xerces 2.11.0 which introduced some new behavior in XMLSchemaValidator.findSchemaGrammar(). The problem is that if there are schemas in the grammar pool with a matching namespace, Xerces does not follow the schema location hints anymore unless the following feature is enabled:
http://apache.org/xml/features/namespace-growth
After enabling this feature, I got conflicts because of duplicate schemas, so I enabled also:
http://apache.org/xml/features/internal/tolerate-duplicates
However, that resulted in the ArrayIndexOutOfBoundsException described above.
