> However, RI always returns the same reference for the same Charset, no matter using "alias"
or "canonical" name as parameter. 
> RI 5.0 passes the following test case, while Harmony fails.
> =============================== Test case ====================
>                      /*
> 	 * test forName: invoke forName two times with the same canonical name,
> 	 * it should return the same reference.
> 	 */
> 	public void testForName_TwoSameRef1(){
> 		Charset cs1 = Charset.forName("UTF-8");
> 		Charset cs2 = Charset.forName("UTF-8");
> 		assertSame(cs1,cs2);
> 	}
> 	
> 	/*
> 	 * test forName: invoke forName two times for the same Charset using canonical name
and alias,
> 	 * it should return the same reference.
> 	 */
> 	public void testForName_TwoSameRef2(){
> 		Charset cs1 = Charset.forName("ASCII");
> 		Charset cs2 = Charset.forName("US-ASCII");
> 		assertSame(cs1,cs2);
