Subject Re: [lang] Thread safety annotations
Date Mon, 28 Nov 2016 02:39:18 GMT
If you're going to share the annotations between projects, why not use a
JSR package for it like the google one? I thought the idea of embedding the
annotations in [lang] was to prevent the need for the dependency and to use
it internally, not as a public annotation for other projects to use.
