Hi Norman,

Thank you very much for the great help!  Glad to know it works for you.

For the SSLEngine.setUSeClientMode() issues, the 
SSLEngine.beginHandshake() spec is expected to throw 
IllegalStateException if the client/server mode has not yet been set.
https://docs.oracle.com/javase/10/docs/api/index.html?overview-summary.html

I will make more evaluation about this behavior change.

Thanks,
Xuelei
