Unexpected NPE is thrown in cases when null passed as element of options array, for example
Files.newBufferedWriter(myPath, new OpenOption[]{null})
Files.newBufferedWriter(myPath, new OpenOption[]{null, StandardOpenOption.CREATE})

java.nio.file package's spec (http://jre.us.oracle.com/java/re/jdk/9/promoted/all/b35/docs/api/java/nio/file/package-summary.html
) says that


"Unless otherwise noted, passing a null argument to a constructor or method of any class or interface in this package will cause a NullPointerException to be thrown.
Additionally, invoking a method with a collection containing a null element will cause a NullPointerException, unless otherwise specified."

As we think it would be great to specify that NPE will be thrown in case of null-elements in array too.
