Correct.

The "system" modules are exactly those built-in to a run-time image,
though we should make that clearer in the API specification.

If you want a module finder for just the Java SE Platform modules,
or for all non-application system modules (i.e., SE + JDK), then
it's pretty easy to construct a filtering module finder to do that.

Do you think such finder(s) should be provided by the API?
