[classlib][crypto] compatibility: CipherOutputStream().close() throws the IllegalStateException
on RI and the NPE on Harmony
----------------------------------------------------------------------------------------------------------------------------

                 Key: HARMONY-1139
                 URL: http://issues.apache.org/jira/browse/HARMONY-1139
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Vladimir Ivanov
            Priority: Minor


The method CipherOutputStream().close()  throws NPE on Harmony and IllegalStateException on
RI if stream is 'null'.

======================= test.java ======================
import javax.crypto.*;
import java.io.*;

public class test  { 
    public static void main (String[] args) throws Exception {
        testCipherOutputStream ch = new testCipherOutputStream((OutputStream) null);
        new CipherOutputStream(ch, Cipher.getInstance("DES/CBC/PKCS5Padding")).close();  
   }
}
class testCipherOutputStream extends CipherOutputStream {
     testCipherOutputStream( OutputStream s){
         super(s);  
     }
}
====================================================

Output:
