RFR [13] JDK-8219389: Delegated task created by SSLEngine throws BufferUnderflowException

[Xuelei Fan]

Hi Tony or Jamil,

Would you please review the following update:
    http://cr.openjdk.java.net/~xuelei/8219389/webrev.00/

BufferUnderflowException might be thrown if the record format does not 
confirm to the formal protocol syntax. The original bug was reported for 
the ClientHello handshake message, and was fixed in JDK-8215790.  I made 
an enhancement so that more handshake messages buffer operating 
RuntimeException could be handled properly.

Thanks,
Xuelei
