Why aren't addmods and limitmods allowed be specified more than once
on the command line and handled like the other ones?
It's last one wins, typical for most options when repeated. I could
imagine someone composing a command line with --add-modules coming from
multiple sources, they logically merge/union, so maybe there is a case
for that. However --limit-modules is niche and I don't think makes sense
to attempt to merge.
We should add an option -XX:+UseUnsafe to be a shortcut for this:
--add-exports=java.base/jdk.internal.misc=ALL-UNNAMED
That may be useful for JDK tests but it makes it too easy to get to
jdk.internal.misc.Unsafe. For usages outside of the JDK then I think
they should continue to use sun.misc.Unsafe (JEP 260 etc.) and gradually
reduce that over time as better approaches are available in the platform.
