Subject [jira] [Created] (IVY-1400) NullPointerException - problem while listing resources
Date Tue, 29 Jan 2013 09:45:22 GMT
Frédéric RIVIERE created IVY-1400:

             Summary: NullPointerException - problem while listing resources
                 Key: IVY-1400
             Project: Ivy
          Issue Type: Bug
    Affects Versions: 2.3.0
            Reporter: Frédéric RIVIERE
            Priority: Minor

After debugging, the problem appears when using org.apache.ivy.util.url.HttpClientHandler
(connecting jakarta commons http client). 

A check is missing in getURLInfo() when web server does not return content-type in HTTP header.
Line 156, method.getResponseHeader("content-type") returns null so NPE occurs when calling

Works fine with BasicURLHandler.

Should be something like:

public URLInfo getURLInfo(URL url, int timeout) {
if (checkStatusCode(url, method)) {
                HttpResponseHeader h = method.getResponseHeader("content-type");
                String contentType = h == null ? null : h.getValue();

                String bodyCharset = BasicURLHandler.getCharSetFromContentType(contentType);
