Description

I Upgraded WSS4J 1.6.1 to WSS4J 2.0.0. The main motive was to encrypt passwords in crypto properties file.

Let me paste the configuration. It is as below.

<jaxws:inInterceptors>

<bean class="org.apache.cxf.ws.security.wss4j.WSS4JStaxInInterceptor">

<constructor-arg>
<map>
<entry
key="#

{T(org.apache.wss4j.dom.handler.WSHandlerConstants).ACTION}

"
value="SAMLTokenSigned" />

<entry key="faultStackTraceEnabled" value="true" />

<entry key="signaturePropFile" value="${cloudenv}.ess.properties" />
<entry key="passwordCallbackClass" value="com.uhg.optuminsight.pim.service.ws.interceptor.SAMLSecurityCallback" />
</map>
</constructor-arg>
</bean>
<bean class="com.uhg.optuminsight.pim.service.ws.interceptor.WebServiceInterceptor" />

</jaxws:inInterceptors>

<jaxws:properties>
<entry key="ws-security.signature.properties" value="${cloudenv}.ess.properties" />
<entry key="ws-security.saml2.validator">
<ref bean="samlTokenValidator" />
</entry>
<entry key="jaxb.encoding" value="UTF-8"/>
<entry key="schema-validation-enabled" value="true" />
</jaxws:properties>

Let me put the Soap Header request.It is as below

</soap:Header>

So the issue is the same Header works like charm when I use WSS4JInInterceptor. But when i try to use WSS4JStaxInInterceptor. I get NullPointer Exception. The exception occurs during the org.apache.cxf.binding.soap.interceptor.ReadHeadersInterceptor phase. The exception occurs at the below line of
if (xmlReader.getEventType() == XMLStreamConstants.START_ELEMENT

xmlReader.nextTag() == XMLStreamConstants.START_ELEMENT)

StackTrace as below.
