----------------------------------------
Summary: NPE when collecting the asserts from a base type
Key: XERCESJ-1610
URL: https://issues.apache.org/jira/browse/XERCESJ-1610
Project: Xerces2-J
Issue Type: Bug
Components: XML Schema 1.1 Structures
Affects Versions: 2.11.0
Reporter: Octavian Nadolu
When I validate the following schema I get a NullPointerException. The
exception occurs because it tries to collect the assertions from a base type,
and the base type does not have a name because is anonymous.
I tested on the xml-schema-1.1-dev branch.
---- schema.xsd------------------------
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";>
