Code review request: 8012082: SASL auth-conf negotiated, but unencrypted data is accepted, reset to unencrypt

[Weijun Wang]

Hi Valerie or Vinnie

Please take a review on this fix

    http://cr.openjdk.java.net/~weijun/8012082/webrev.00/

Bug is

    http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=8012082

The problem is that a single MessageProp is used in all wrap and unwrap 
calls and the output value is not checked.

After the output check, it looks like it's OK to share the MessageProp 
object (because once it's changed, an exception is thrown), but I create 
one for each wrap/unwrap to be safe and clean, and I don't know if there 
are applications trying to "recover" from an exception.

This is not a security issue, it's after the peer establishing the 
security context, therefore already authenticated.

Thanks
Max
