Florian Keller updated XMLBEANS-511:
------------------------------------

    Description: 
I caught following NullPointerException, using XmlBeans Version 2.5:

java.lang.NullPointerException
	at org.apache.xmlbeans.impl.schema.SchemaTypeImpl.isAssignableFrom(SchemaTypeImpl.java:2267)
  at org.apache.xmlbeans.impl.schema.SchemaTypeImpl.createElementType(SchemaTypeImpl.java:1044)
  at org.apache.xmlbeans.impl.values.XmlObjectBase.create_element_user(XmlObjectBase.java:927)
  at org.apache.xmlbeans.impl.store.Xobj.getUser(Xobj.java:1669)
	at org.apache.xmlbeans.impl.store.Xobj.find_element_user(Xobj.java:2074)

Seems, like there's a missing Null-Check.
/xmlbeans/src/typeimpl/org/apache/xmlbeans/impl/schema/SchemaTypeImpl.java, line 2269 \
and following type is set by type.getBaseType() which explicitly may return null. The \
following type.equals(this) produces above seen NPE.
