--add-opens and --add-modules in MANIFEST.MF

[Reto Merz]

Hi,

There is a proposal to support --add-exports in MANIFEST.MF [1].
Are there any plans to support --add-opens and --add-modules also?
The current spec does not list such new attributes [2]. 

I have seen that webstart uses --add-modules ALL-SYSTEM [3].
Wouldn't it make sense to change the default for "java -jar" to ALL-SYSTEM also?
Otherwise there are apps which will no longer start with a simple double click [4].

One more question: Is there are way to list the default modules?
It seems that "java --list-modules" prints all modules
and "java --list-modules ALL-DEFAULT" does not work.

Regards
