[classlib][luni] java.io.BufferedInputStream.skip(0) shouldn't throw IOException
--------------------------------------------------------------------------------

                 Key: HARMONY-6133
                 URL: https://issues.apache.org/jira/browse/HARMONY-6133
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
    Affects Versions: 5.0M8
            Reporter: Kevin Zhou
             Fix For: 5.0M9


Given a test case [1], HY throws a java.lang.IOException [2], while RI passes this test.

Create a BufferedInputStream object using a null InputStream, java.io.BufferedInputStream.skip(0)
should not throw IOException. 
While at this case, java.io.BufferedInputStream.skip(Value > 0) should throw IOException.


[1] Test Case :
public void test_skip_scenario1() throws IOException {
    BufferedInputStream buf = new BufferedInputStream(null, 5);
    assertEquals(0, buf.skip(0));
}

public void test_skip_scenario2() throws IOException {
    BufferedInputStream buf = new BufferedInputStream(null, 5);
    try {
        buf.skip(1);
        fail("should throw IOException");
    } catch (IOException e) {
        // Expected
    }
}

[2] Stack Trace:
java.io.IOException: Stream is closed
at java.io.BufferedInputStream.skip(BufferedInputStream.java:346)
