/**
* Java SE bootstrap example with explicit configuration.
*
* This example demonstrates bootstrapping on Java SE platforms using hardly no defaults at all (besides JSSE defaults).
* It applies parameters passed at the command line.
*
*
* Depending of the actual parameters passed at the command line (i. e. with protocol set up {@code HTTPS}), this
* example might need to have additional external JSSE configuration:
*
*
* - {@code javax.net.ssl.keyStore=~/.keystore} - HTTPS: Path to a keystore holding an X.509 certificate for
* {@code CN=localhost}
* - {@code javax.net.ssl.keyStorePassword=...} - HTTPS: Password of that keystore
*
