I more expected a buffer underflow....when I pass all 100 bytes, it works fine.Test should be easy for anyone ...

The fact that a handshake is needed on a close is a real pain. Basically, I have an nio abstraction and close is called on the MyTCPChannel and I know must block while a handshake goes on, or make the close asynchronous like sopublic void close(CloseCallback c);Is it bad to just not even close ...

In the docs I read "New handshaking data can be intermixed among the application data"I can't seem to get that too work. Below is alot of code all of which works except the very last line. There are only two logs in this file and I paste those after the code too. Notice SSLEngine for some ...

I have been dealing with this for days and finally wrote a JUnit test just against the SSLEngine itself. I am about to file a bug report, but can someone please verify that they are having the same problem.Basically, on a rehanshake, just after a Runnable is retrieved and before it is run, the ...
