Can you try this:

if (type == UserDefinedFileAttributeView.class) { 
    UnixPath file = UnixPath.toUnixPath(obj);
    return supportsUserDefinedFileAttributeView(file) ? ..

That will remove the cast/check from supportsUserDefinedFileAttributeView and also ensure that ProviderMismatchException is thrown if called with a Path from a different provider.

[TheRealMDoerr]

I like this version much better. Changed.

[TheRealMDoerr]

Thanks for the review and your guidance!
