No, and there shouldn't be any such code. However, this is visible to
the application if running without the security manager.

Note that there are functions that start-domain does that "java -jar"
doesn't, such as prompting for an admin password if it is set to reset.
A java -jar in that case will just not start the server.
Another difference has to do with instance or DAS restart. If using java
-jar, the restart command doesn't know what options were passed in to
the server, so it will use defaults. If started with start-domain or
start-local-instance, the instance will be restarted with the same
options that were used to start it.
