Subject Re: [DISCUSS] Assume Private-Unstable for classes that are not annotated
Date Fri, 25 Jul 2014 04:34:17 GMT
+1 for the proposal.

I believe stating that "classes without annotations are implicitly private"
is consistent with what we publish for our JavaDocs.
 IncludePublicAnnotationsStandardDoclet, used in the root pom.xml, filters
out classes that don't explicitly have the Public annotation.
