Code Review Request, JDK-8213782: NullPointerException in sun.security.ssl.OutputRecord.changeWriteCiphers

[Xue-Lei Fan]

Hi,

Could I have the fix reviewed?
    http://cr.openjdk.java.net/~xuelei/8213782/webrev.00/

The SSLCipher.createReadCipher() and createWriteCipher() could return 
null if the cipher is not supported or the cipher is not available for a 
certain protocol version.  The caller should check the null value, and 
send back a "illegal_parameter" alert for such cases.

I did not add new regression test. The update is straightforward, while 
constructing an illegal handshake message for such cases is complicated.

Thanks,
Xuelei
