[Bug classpath/23974] New: new File( "name\\" ).getName() returns "" instead of "name"

[trygvis at inamo dot no]

Even though the current behaviour seems like the most consistent behaviour it's 
unconsistent with Sun's behaviour.

To illustrate the problem, add this to mauve/gnu/testlet/java/io/File/newFile.
java:

        harness.check(new File("dir").getName(), "dir", "getName(): returns the 
argument" );
        harness.check(new File("dir/").getName(), "dir", "getName(): dir/");
        harness.check(new File("dir\\").getName(), "dir\\", "getName(): dir\\");

Output with jamvm:

    [mauve] PASS: gnu.testlet.java.io.File.newFile: getName(): dir/ (number 1)
    [mauve] FAIL: gnu.testlet.java.io.File.newFile: getName(): dir\ (number 1)
    [mauve] got  but expected dir\

Output with java:

    [mauve] PASS: gnu.testlet.java.io.File.newFile: getName(): dir/ (number 1)
    [mauve] PASS: gnu.testlet.java.io.File.newFile: getName(): dir\ (number 1)

The code that made this issue come up was this testcase from commons-io:

    public void testPrefix() throws Exception {
        IOFileFilter filter = new PrefixFileFilter(new String[] { "foo", "bar" 
});
        assertFiltering(filter, new File("foo.test"), true);
        assertFiltering(filter, new File("FOO.test"), false);  //case-sensitive
        assertFiltering(filter, new File("foo"), true);
        assertFiltering(filter, new File("bar"), true);
        assertFiltering(filter, new File("food/"), true);
        assertFiltering(filter, new File("barred\\"), true);
        assertFiltering(filter, new File("test"), false);
        assertFiltering(filter, new File("fo_o.test"), false);
        assertFiltering(filter, new File("abar.exe"), false);

        filter = new PrefixFileFilter("tes");
        assertFiltering(filter, new File("test"), true);
        assertFiltering(filter, new File("fred"), false);

        try {
            new PrefixFileFilter((String) null);
            fail();
        } catch (IllegalArgumentException ex) {
        }
    }

I will check in the commons-io debian package today in pkg-java project on 
alioth.debian.org including a patch to comment out the test case, but just 
remove the patch and the issue should show up.
