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

[Xuelei Fan]

Hi Tony,

Would you mind make it clear that this impact the JDK JSSE provider 
only?  Third party's provider may be able to support DTLS with SSLSocket.

I think there may be no specification change.  The 
SSLContext.getServerSocketFactory() and SSLContext.getSocketFactory() 
defines the spec if the algorithm is not supported by the underlying 
provider, "UnsupportedOperationException - if the underlying provider 
does not implement the operation.".  I may prefer to make it clear that 
this is just a behavior change of the JDK JSSE provider (SunJSSE).  The 
SunJSSE provider now throws UnsupportedOperationException for creating 
SSL(Server)SocketFactory with DTLS SSLContext, because it does not 
actually support DTLS SSLSocket.

In Solution section, "Throwing a UnsupportedOperationException when 
getting a socket from the SSLServerSocketFactory or SSLSocketFactory for 
DTLS."   I guess you meant, throwing a UOE when calling 
SSLContext.getServerSocketFactory() and SSLContext.getSocketFactory()?

Thanks,
Xuelei
