Hello Jeanfrancois,

Thanks for the help,
doing SelectorThread.setWebAppRootPath("/dev/null");
solves the SEVERE error problem.
I've posted an issue as you asked and assigned it to you(hope that is ok).
Can you or someone else help me with HTTPS support part?
I can not find example with SSLSelectorThread used on the server side.
I tried configuring it with SSLConfig and then do same thing as with
EmbeddedServer.

Here is my code for this, I get browser prompt about certificate but service
metod is never called.
Is it a problem with algorithm, or am I using this completly wrong.
I'm trying to do same thing as with EmbeddedServer, just to call it and get
response but over HTTPS,
again not static content is served.
