FileRef.checkAccess(null) throws IAE in Win and NPE in Sol?

[Rajendra Gutupalli]

Hi Alan,

I started changing my test cases to sync with b94. I did a quick test 
with Path.checkAccess(null) and observed it throws IAE in windows and 
NPE in Solaris for the Argument null.
Should it throw NPE in Windows?

Windows:
Exception in thread "main" java.lang.IllegalArgumentException
        at sun.nio.fs.WindowsPath.checkAccess(WindowsPath.java:726)
        at adhoc.CheckAccess.main(CheckAccess.java:15)

Solaris:
Exception in thread "main" java.lang.NullPointerException
        at sun.nio.fs.UnixPath.checkAccess(UnixPath.java:776)
        at TestAccess.main(TestAccess.java:7)

Thanks
Rajendra.
