Description

This is related to the changes for CXF-4814 [1]. I get the following exception

java.lang.NullPointerException
	at org.apache.cxf.ws.policy.WSPolicyFeature.resolveLocal(WSPolicyFeature.java:236)

when dealing with a spring descriptor as follows:

...
<wsp:Policy wsu:Id="RM" xmlns:wsp="http://www.w3.org/ns/ws-policy" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
    <wsam:Addressing xmlns:wsam="http://www.w3.org/2007/02/addressing/metadata">
      <wsp:Policy/>
    </wsam:Addressing>
    <wsrmp:RMAssertion xmlns:wsrmp="http://schemas.xmlsoap.org/ws/2005/02/rm/policy">
      <wsrmp:BaseRetransmissionInterval Milliseconds="10000"/>
    </wsrmp:RMAssertion>
  </wsp:Policy>
  
  <jaxws:endpoint id='TestService' address='http://@jboss.bind.address@:8080/jaxws-cxf-wsrm-basic-rpc' implementor='org.jboss.test.ws.jaxws.cxf.wsrm.BasicRPCEndpointImpl'>
    <jaxws:features>
      <p:policies>
        <wsp:PolicyReference URI="#RM" xmlns:wsp="http://www.w3.org/ns/ws-policy"/>
      </p:policies>
    </jaxws:features>
  </jaxws:endpoint>
...

It seems like the code in WSPolicyFeature::resolveLocal(PolicyReference ref, final Bus bus, DescriptionInfo i) is trying to access the current DescriptionInfo, while that will only be set later in WSPolicyFeature::initialize(Server server, Bus bus) (using the ServiceModelPolicyUpdater::addPolicyAttachments and ServiceModelPolicyUpdater::addPolicy methods)
