Correct Alan, resolve(Path) is working as you mentioned. But the other 
overloaded resolve(String) is not allowing me to pass null.
The following code snippet is throwing NPE when tried in Solaris and 
Windows.

<code>
Path path = Paths.get("c:/");
out.println(path.resolve((String)null));
</code>

Could you please me know what should be the output in the above case?. I 
am getting NPE instead of printing path "c:".

Thanks
