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
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.
Greetings
