Component/s: XML Schema 1.1 Structures
> NullPointerException caused by XMLSchemaValidator.addDefaultAttributes

>
> Key: XERCESJ-1488
> URL: https://issues.apache.org/jira/browse/XERCESJ-1488
> Project: Xerces2-J
> Issue Type: Bug
> Components: XML Schema 1.1 Structures
> Affects Versions: 2.11.0
> Environment: Java version: 1.6.0_23
> Java home: C:\Program Files\Java\jdk1.6.0_23\jre
> Default locale: en_US, platform encoding: Cp1252
> OS name: "windows vista" version: "6.0" arch: "amd64" Family: "windows"
> Reporter: Gary Gregory
> Priority: Blocker
>
> The following is a regression from 2.10 because our unit tests run OK with
> 2.10 and blow up with 2.11.
> NullPointerException caused by XMLSchemaValidator.addDefaultAttributes
> Note that the second argument is null in the call:
> {noformat}
> if (XSTypeHelper.isAtomicValueValidForAnUnion(attDV.getMemberTypes(),
> null, defaultValue)) {
> {noformat}
> at
> XMLSchemaValidator.addDefaultAttributes(QName, XMLAttributes,
> XSAttributeGroupDecl) line: 3385
> Which means that at this point in the call chain:
> {noformat}
