      Description

        FULL PRODUCT VERSION :
        All of JDK 8, JDK7 u51 and OpenJDK 7u51 have the problem

        ADDITIONAL OS VERSION INFORMATION :
        Ubuntu Linux 13.10, x86-64

        A DESCRIPTION OF THE PROBLEM :
        fge@alustriel:/tmp$ cat Foo.java
        import java.nio.file.Paths;


        public class Foo
        {
            public static void main(final String... args)
            {
                System.out.printf("'%s'\n", Paths.get("").normalize());
                System.exit(0);
            }
        }
        fge@alustriel:/tmp$ javac Foo.java
        fge@alustriel:/tmp$ java Foo
        Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0
        at sun.nio.fs.UnixPath.normalize(UnixPath.java:508)

        REGRESSION. Last worked in version 6u45

        ADDITIONAL REGRESSION INFORMATION:
        Does NOT happen on Windows systems. I don't have other Unix systems than Linux to test on.

        I only discovered the bug recently... I set the "prior working release" to the latest JDK 6 version since it didn't have Path...
