Looks very good! I have two comments/questions.
1. I thought we agreed that *some* tests should be in the same package as implementations. How this fits together with a special package name for tests? 2. Does not it sound too strict: "module developers who modify code that is not in an internal package must do so in a manner that ensures Java binary compatibility"? How about "... should avoid breaking Java binary compatibility and must check that the change does not break other modules" Thanks, Mikhail Loenko Intel Middleware Products Division On 2/13/06, Tim Ellison <[EMAIL PROTECTED]> wrote: > I've put a first cut of the proposed package naming convention on the > website: > > http://incubator.apache.org/harmony/subcomponents/classlibrary/pkgnaming.html > > Regards, > Tim > > Leo Simons wrote: > > On Fri, Feb 10, 2006 at 12:52:09PM +0300, Anton Avtamonov wrote: > >>> As I wrote elsewhere, I propose that packages whose naming convention is: > >>> org.apache.harmony.<modulename>.<something> > >>> > >>> represent internal APIs.
