CSR Review: 8208641: SSLSocket should throw an exception when configuring DTLS

[Xuelei Fan]

Hi Tony,

The Specification section looks more like the implementation details. 
We may change the implementation details again in the future.  It may be 
more suitable to move it to the Solution section, or just remove it.  In 
the Specification section, I may just say something like, "No APIs 
changes.  The SunJSSE provider is updated to throw 
UnsupportedOperationException if  SSLContext.SSLServerSocketFactory() or 
SSLContext.SSLSocketFactory() get called for DTLS algorithms SSLContext".

Thanks,
Xuelei
