Michael Glavassevich resolved XERCESJ-1159:
-------------------------------------------
Resolution: Fixed
This bug had been lurking since annotation support was added to the parser many
releases ago. Should be fixed in SVN now.
> NullPointerException when a pattern has a annotation and the simple type is
inheirted and a new pattern is added

> Key: XERCESJ-1159
> URL: http://issues.apache.org/jira/browse/XERCESJ-1159
> Project: Xerces2-J
> Type: Bug
> Components: XML Schema Structures, XML Schema datatypes, XML Schema API
> Versions: 2.6.2, 2.7.1, 2.8.0
> Environment: Java 1.4.2_01, Java 1.5.0_06
> Reporter: Rudolf Pfister
> Assignee: Michael Glavassevich
>
> I wrote a Schema with a simpleType 'token' which has a pattern-facet.
> In the Schema there is a second type 'className' restricts 'token' with a
further pattern.
> Both pattern-elements has annotation-elements. (See Schema below.)
> Validating an XML against this schema causes a NullpointerException (see
below also).
> When removing the annotation of the patterns it works, but I loss the
documentation of the patterns, which sometimes may very cryptical.
