The "--java-options" jpackage option can be used to send any argument to the jli launcher, but some options conflict with the options automatically generated by jpackage.
The intent of this enhancement is to document those (possibly) conflicting options:
--module (or -m)
--module-path (or -p_
--class-path (or -classpath, or -cp, or -Djava.classpath=...)
-jar
