The CLI options to export or open packages can be specified in JNLP file,
you shouldn't need to ask user to add them via the control panel. You can
predicate on the Java SE version too, i.e.
<j2se version="9+" java-vm-args="--add-opens=..." />
The issue is the limit on the *number* of args we can have in the
java-vm-args. If you exceed the limit, the webstart app fails to launch
and displays a popup window with the text "too many args to run".
We need so many --add-exports and --add-opens that it's possible we won't
be able to fit them all in there. At the moment, we are just under the
limit and I'm hoping further testing of our app doesn't push us over the
edge by revealing more --add-opens, for example.
I can't shrink the list of args by using --illegal-access=permit, because
that is disallowed in the jnlp. I think I saw some correspondence from you
indicating you intentionally wanted the jnlp to explicitly list what was
needed. Unfortunately, that won't work if you have too many to list.
Any chance you could change Java 9 to allow --illegal-access=permit in the
jnlp or alternatively increase the number of args allowed?
I think that this problem could be solved by WebStart composing the JVM
arguments into a temporary file and using the new JDK 9 @<filepath>
syntax to launch the app.
Any chance that WebStart gets open-sourced?
