Running "java -jar" is not embedded. Embedded is when you start V3
inside your own running JVM. There is a different API for embedded.

java -jar is a simple way to start V3. You don't get any
launcher-support this way (jvm-options, token substitution, etc .)

I'm also thinking that no user of server-instances would want to start
it that way...

The reason it came up is that the V3 bootstrap has to know *what* it is
starting. If instances are always started via asadmin it will be easy.
If java -jar is supported then it will be harder.
