The changes look good to me.  I just noticed a couple small things in 
the test:

test/jdk/java/io/InputStream/NullInputStream.java

  109     @Test(groups = "open")
  110     public static void testreadNBytes() {
  111         try {
  112             assertEquals(0, openStream.readNBytes(new byte[1], 0, 1),
  113                 "readNBytes(byte[],int,int) != -1");

Line 113 should read "... != 0", yes?

  129     @Test(groups = "open")
  130     public static void testSkip() {
  131         try {
  132             assertEquals(0, openStream.skip(1), "transferTo() != 0");

On 132, it's "skip() != 0".
