Infrastructure

I had a piece of java client code which talked with CNs and it worked. However, it stopped working on the second day. I didn't change anything in my code. The error message was the cn list hasn't been initialized.
I turned on the ssl debug and saw the error message:
[junit] main, handling exception: java.security.ProviderException: java.security.InvalidKeyException: EC parameters error
[junit] %% Invalidated: [Session-1, TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA]
[junit] main, SEND TLSv1.2 ALERT: fatal, description = internal_error
[junit] main, WRITE: TLSv1.2 Alert, length = 2
[junit] [Raw write]: length = 7
[junit] 0000: 15 03 03 00 02 02 50 ......P
[junit] main, called closeSocket()
[junit] @build.context@ 20170519-11:52:15: [DEBUG]: http-outgoing-0: Shutdown connection

It wasn't very helpful.

I also wrote a simple version of the client code. It seems the d1_libclient_java couldn't talk with any server. But this time the error message made more sense:
