[classlib][security]javax.crypto.spec.CipherOutputStream.write(byte[], 0, 0)  throws  IllegalStateException
while RI does not

         Key: HARMONY-758
         URL: http://issues.apache.org/jira/browse/HARMONY-758
     Project: Harmony
        Type: Bug

  Components: Classlib  
    Reporter: Vladimir Ivanov

The Harmony method javax.crypto.spec.CipherOutputStream.write(byte[], 0, 0) throws  IllegalStateException
while RI does not
Seems, it related to the issue 757 to add boundary checks before main action.

          CipherOutputStream stream1 = new CipherOutputStream(new BufferedOutputStream((OutputStream)
null), nc);
          CipherOutputStream stream2 = new CipherOutputStream(stream1, cf);
          CipherOutputStream stream3 = new CipherOutputStream(stream2, nc);
          stream3.write(new byte[] {0}, 0, 0);
       } catch (Exception e) {
