Radu Coravu created XERCESJ-1566:
------------------------------------
Summary: java.lang.NullPointerException when validating against
WSDL Schema
Key: XERCESJ-1566
URL: https://issues.apache.org/jira/browse/XERCESJ-1566
Project: Xerces2-J
Issue Type: Bug
Affects Versions: 2.11.0
Reporter: Radu Coravu
I'm integrating "Xerces-J 2.11.0-xml-schema-1.1-beta" in Oxygen XML Editor.
After the integration one of our automated tests caught this NPE:
-------------------------------------
java.lang.NullPointerException

--------------------------------------
Basically the XMLSchemaValidator has some code like:
-----------------------
if (attDV.getVariety() ==
XSSimpleTypeDefinition.VARIETY_UNION) {
if
(XSTypeHelper.isAtomicValueValidForAnUnion(attDV.getMemberTypes(),
null,
defaultValue)) {
fisAtomicValueValid = false;
}
}
-------------------------
which sends a "null" value to the content parameter of
"isAtomicValueValidForAnUnion" which later generates the NPE.
I will attach a WSDL file (the problem seems to happen when validating any WSDL
file) and the "wsdl11soap11.xsd" schema.
