java.nio.CharBuffer.wrap(char[], int, int) throws unexpected
IllegalArgumentException with empty character array.

Here is the example:

------test.java----

import java.nio.*;

class t {
    public static void main (String [] args) {
        char [] array = new char[0];
        try {
            CharBuffer.wrap(array,1,2);
            System.out.println("IndexOutOfBoundsException was expected");
            return;
        } catch (IndexOutOfBoundsException e) {
        }
    }
}

-----output:----

#java -version
java version "1.4.0-beta3"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-beta3-b81)
Java HotSpot(TM) Client VM (build 1.4.0-beta3-b81, mixed mode)

#java test

Exception in thread "main" java.lang.IllegalArgumentException
        at java.nio.Buffer.limit(Buffer.java:239)

        at java.nio.CharBuffer.<init>(CharBuffer.java:229)
        at java.nio.HeapCharBuffer.<init>(HeapCharBuffer.java:47)
        at java.nio.CharBuffer.wrap(CharBuffer.java:298)
        at test.main(test.java:7)

Following methods also fails due to this reason:

java.nio.ByteBuffer.wrap(char[], int, int)
java.nio.DoubleBuffer.wrap(char[], int, int)
java.nio.FloatBuffer.wrap(char[], int, int)
java.nio.IntBuffer.wrap(char[], int, int)
java.nio.LongBuffer.wrap(char[], int, int)
java.nio.ShortBuffer.wrap(char[], int, int)
