- When [] moves to Java 8, compatible_with=appengine targets will remain on Java 7. (If this target is a non-java_* target, you can ignore this bullet.)
- compatible_with=appengine targets can depend only on other compatible_with=appengine targets. (Fortunately, most common libraries will be compatible_with=appengine: []
This CL is one of thousands in a migration on the critical path for Java 8, so please respond promptly, and, if you are the wrong reviewer, please reassign the CL.
