      1. Enable StoredResponseHandler (store-response) with RequestDumpingHandler (dump-request) to dump request and response information (both header and body) in the undertow subsystem in standalone.xml

          <server name="default-server">
        ... 
        <host name="default-host" alias="localhost">
            ... 
            <filter-ref name="dump-request-and-response-filter"/> <!-- add this --> 
        </host>
    </server>
    ... 
    <filters>
        <expression-filter name="dump-request-and-response-filter" expression="dump-request;eager-form-parser;store-response;"/> <!-- add this --> 
    </filters>

      2. Deploy a web application like https://github.com/jboss-developer/jboss-eap-quickstarts/tree/7.3.x/helloworld-rs

      3. Send a request 

      $ curl -v http://localhost:8080/helloworld-rs/rest/xml

      RequestDumpingHandler works fine to dump request/response in sever.log, but you will see NullPointerException at io.undertow.conduits.StoredResponseStreamSinkConduit.terminateWrites().

    Description

      When StoredResponseHandler (store-response) is enabled to dump response body with RequestDumpingHandler (dump-request), NullPointerException happens at io.undertow.conduits.StoredResponseStreamSinkConduit.terminateWrites() at the end of the request processing.

          Bug - A problem that impairs or prevents the functions of the product. UNDERTOW-1849 NPE happens at StoredResponseStreamSinkConduit.terminateWrites when StoredResponseHandler (store-response) is enabled

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
