> 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 getValue().
> 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);
> ...
