Hello,

When I give a null InputStream to Builder.build(), I get a
MalformedURLException which is misleading when debugging the problem:

java.net.MalformedURLException
at java.net.URL.<init>(Unknown Source)

It would be much easier to find the real cause of the problem if an NPE with
a corresponding message would be thrown.
