sure, I will do that in the future if that is then the way to go.
Because before (maybe a year ago) I was told to post to the dev list
instead.

Hi Jochen,
If you want to comment on a thread on the expert group list then you
really need to post that comment to the observers or comments list.
Posting it here without any context is just going to confuse people who
don't read the expert group list
n.b. I am replying to the jigsaw-dev list rather than just to you
directly so as to clarify the provenance of your post for those who are
still as confused as I was until I found David's original note on the
expert group list.
regards,
Andrew Dinn

It's clear that modules are not to be treated like classes, because (for
example) circularity among modules is considered "bad" whereas
circularity among classes has been shown to be indispensable, and
classes within a class loader or module are loaded and resolved lazily
whereas modules are loaded and resolved aggressively, etc. But I see
your point that only "special" citizens ought to mutate a module. I
agree, but I do not think this should be limited to agents: containers
also have a similar need for similar reasons.
and I would not simply limit this to containers as well. If you have a
programming language runtime for example you have an element, that will
have to do similar tasks to what Java internals will want to do.. for
example proxies. But the big difference is, that we are not containing
the classes we do the work for. The modules containing those might even
be loaded already and instances of those classes may already exist.
I was told an agent can mutate the module information. And I don't
understand if an agent can do it, why a normal method cannot... or what
makes a citizen "special" enough to be able to do it. On the contrary
this discussion now gives me the impression an agent cannot mutate the
module after it came into existence without duplicating classes. Clearly
I had yet no time to actually try this :(
