             Summary: NullPointerException in getContentLengthValue (HeadMethodHandler.java:100)
                 Key: WINK-425
                 URL: https://issues.apache.org/jira/browse/WINK-425
             Project: Wink
          Issue Type: Bug
          Components: Server
    Affects Versions: 1.4
         Environment: Ubuntu 14.04 LTS, Apache 2.4.7, Tomcat 7, Wink 1.4
            Reporter: Slawomir Lisznianski


I'd like to reopen bug WINK-357 reported on 11/Jan/12. 

A web crawler hitting any of my resources with a HEAD request will cause this error since countingStream is NULL here:

{code:java}
HeadMethodHandler.java:100:
getContentLengthValue() {
  return countingStream.getByteCount();
}
{code}

One should not be required to handle HEAD requests only to avoid this bug from being exposed. 

{code:xml}
