-classpath vs --class-path

 Hi,

during experimentation I encountered compiler behavior that I found
rather strange: It looks like the -classpath and --class-path options do
not behave the same way.

In my experiment I create a bunch of modules in 'mods' and then create
the last one by putting the modules on the class path (no reason, just
playing around):

    javac -cp "mods/*" -d classes/advent src/advent/advent/Main.java

This works and '-classpath' does, too, but '--class-path' doesn't. In
that case the compiler complains that the packages contained by the
modules in 'mods' do not exist.

For an executable version see here:

	https://github.com/CodeFX-org/demo-jigsaw-advent-calendar/blob/compiling-with-deps-as-modules/compileAndRun.sh#L41-L48

I noticed this on b146 but it also exists in b148; both EA-Jigsaw builds.

 so long ... Nicolai
