[classlib][io] compatibility: RI throws OOME while HARMONY throws NPE
---------------------------------------------------------------------

                 Key: HARMONY-1095
                 URL: http://issues.apache.org/jira/browse/HARMONY-1095
             Project: Harmony
          Issue Type: Bug
          Components: Non-bug differences from RI
            Reporter: Vladimir Ivanov
            Priority: Minor
         Attachments: CharArrayWriter.patch

The Harmony method new CharArrayWriter().write(String, int, Integer.MAX_VALUE) throws NPE
while RI throws OOME.
Seems, it is RI bug.
But for Harmony message or exception should be fixed.

======================= test.java ===================
import java.io.CharArrayWriter;

public class test {
    public static void main(String args[]) {
        new CharArrayWriter().write((String) null, 4, Integer.MAX_VALUE);
    }
}
