Bug or not bug? Files.newInputStream() on a Path which is a directory does not fail until you read from it

By the way, this is running 1.7.0u72 from Oracle; the result is the
same with 1.8.0u25.

I've had a report of a similar error on Mac OS X 10.10.1, 1.8.0u25.

>From a cursory analysis of the stack trace, it seems to me as the
implementation is common to both of them, and that the stream is not
actually opened until the first time it is read, and that open(2)
returns -EISDIR; hence the error message...
