XPath-Query 1.0 throws NullpointerException

[Stephan Burkard]

Hi 

Given an XML document without namespaces: 

<?xml version="1.0" encoding="UTF-8" ?>
<document/>

and I query with XPath 1.0 for the namespace: 

The XPath assertion fails, the policy immediately aborts and the client gets a NullpointerException:

<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope
    xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
    xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <soapenv:Body>
        <soapenv:Fault>
            <faultcode>Server</faultcode>
            <faultstring>java.lang.NullPointerException</faultstring>
            <faultactor/>
            <detail/>
        </soapenv:Fault>
    </soapenv:Body>
</soapenv:Envelope>

 

When I do exactly the same but with XPath 2.0, it works perfectly. 

 

Throwing an Exception and therefore immediately aborting the policy is a bit rude :-)

I guess the NPE is thrown by the underlying Java Library but it should be catched so that only the assertion fails. 

 

PS: Happens like this on Gateway 8.3.01

From Case notes 

 

The described behavior is related to the XPath error handling and should be expected.
The error handling has been enhanced in XPath 2.0.
