Steps to Reproduce:
Hide

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"/>  </host> </server> ... <filters> <expression-filter name="dump-request-and-response-filter" expression="dump-request;eager-form-parser;store-response;"/>  </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().

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.
