notes on varargs

[Samuel Audet]

Where can I find this "basic charter"? Last time that I requested access to
these documents, everyone told me none existed. So, do they exist
somewhere? And if so, where can the community (and by that I mean people
both inside and outside Oracle) can read and comment on them? I mean, it's
fine if Oracle decides to do everything by itself, but please make it clear
so that we all know where to stand! Thank you
