A careless bug can crash JXcore when using PSK

The Crash
Bad Code

I did a bad refactoring where the pskIdToSecret callback (which is eventually used as part of a psk Callback) had some unbounded variables inside of it (e.g. variables that weren't defined anywhere) and that caused JXcore to crash.

Where are you calling tls.creatserver. Help if you have a line #

The function causing the crash is here. The problem was that I had screwed up a refactor and pskIdentity and pskKey were not bound to anything. in other words there was no declaration of either variable in any visible scope. Once I fixed that everything was fine. The createserver is called here

Another crash, I'm investigating now.

The new crash btw is in different code. I'll share the code once I figure out what is going on.

O.k. this crash was very similar to the first one. Another programming error from yours truly. IN this case the callback function was:

function (id) {
          return self.pskIdToSecret(id);
}

Where self.pskIdToSecret is undefined. That causes an immediate crash with full stack trace.

BTW, I don't consider this bug to be high priority. That's why it's in IceBox.

Ok. I'll just poke around in other native areas and see how they validate undefined callbacks or undefined values
