Description

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);
...
