HttpException deploying to webdav

When trying to deploy to our webdav maven-repository the following exception occurs:

The access.log of our maven-repository show the following:

This shows that every request without auth-info ist retried with auth-info automatically, but the payload of the PUT request is missing the JAR-content.
In some forum I found the hint that the buffering of the content within http-client can be forced via setting the ContentLength to AUTO.

So I changed the following:
{{
// method.setRequestContentLength( contentLength );
method.setRequestContentLength( PutMethod.CONTENT_LENGTH_AUTO );
}}

This resolves the problem, but I don't know if there are some unwanted side-effects.
