[HARMONY-4196] [classlib][luni] InputStreamReader can't handle UnicodeBig encoding

Description

Consider the following simple test:

import java.io.*;

public class Test {
public static void main(String[] args) {
try {
new InputStreamReader(new ByteArrayInputStream(new byte[]

{(byte) 0xFE, (byte) 0xFF}

), "UnicodeBig");
System.out.println("SUCCESS");
} catch (Throwable e)

{ System.out.println("FAIL:"); e.printStackTrace(System.out); }

}
}

Output on RI:

SUCCESS

Output on Harmony (both DRL VM and IBM VM):

FAIL:
java.io.UnsupportedEncodingException
at java.io.InputStreamReader.<init>(InputStreamReader.java:104)
at Test.main(Test.java:6)

Additional investigation shows that the cause for this exception is:

java.nio.charset.UnsupportedCharsetException: The unsupported charset name is "UnicodeBig".
at java.nio.charset.Charset.forName(Charset.java:564)
at java.io.InputStreamReader.<init>(InputStreamReader.java:99)
at Test.main(Test.java:5)

Interesting point is, the direct call to Charset.forName("UnicodeBig") causes the same exception on RI also.
So it seems the problem is not in Charset but in InputStreamReader itself.
