Description

Align the JVM checking rules with Java language rules for methods, constructors, and fields in nested classes. In particular, allow a class file to access private names of other class files compiled within the scope of a single top-level declaration.  Ensure that class files contain accurate descriptions of class and interface nesting.

The RFR for nestmates has gone out: http://mail.openjdk.java.net/pipermail/hotspot-dev/2018-May/032228.html http://mail.openjdk.java.net/pipermail/serviceability-dev/2018-May/023718.html http://mail.openjdk.java.net/pipermail/core-libs-dev/2018-May/053144.html http://mail.openjdk.java.net/pipermail/compiler-dev/2018-May/011885.html

Initial development is being done in the valhalla repo under the nestmates branch: https://bugs.openjdk.java.net/issues/?jql=project%20%3D%20jdk%20and%20fixVersion%20%3D%20repo-valhalla%20and%20labels%20in%20(%22nestmates%22)

This is the main issue to be used for pushing the nestmate changes to mainline ready for release. Some specific sub-tasks will be added for related work.
07-09-2017
Note: there are a number of tests using inner classes (to simplify tests running in parallel in jteg not having their own directories), that are explicitly testing access controls. These will need to be rewritten.

POC for both 292 and LinkResolver.
09-10-2013
POC patch to JSR 292 to allow nestmate access. Requires a similar patch to JVM code to enable for invocation instructions.

It is JEP 181, which is now published: http://openjdk.java.net/jeps/181
