Enough technical debt has been paid down that we can now create the new JDK-specific module as proposed by JEP 260 [1], named jdk.unsupported. This module will initially contain, and export, the sun.misc package, and will eventually export the sun.reflect package too ( once it has been sanitized ). The jdk.unsupported module will be present in full JRE and JDK images.
http://cr.openjdk.java.net/~chegar/8153737/ https://bugs.openjdk.java.net/browse/JDK-8153737 Summary of the changes: - Restructure, what remains of, the sources in sun/misc to reflect the new modular layout. There are still a few non-Critical APIs in sun.misc that will be addressed later. - Add dependencies from several JDK modules to jdk.unsupported. All dependencies have issues tracking them, and should be removed in 9. - The test library in the top-level repo provides a convenience to tests to retrieve Unsafe. This has been updated to the "real" internal Unsafe, so there are many many tests that require to be updated, mostly the @modules tags. ( The Unsafe dependency in the library should probably be revisited at some point, as it requires many tests, not wishing to use Unsafe, to require an explicit dependency on it ) Note: with recent work from Mikael [2], sun.misc.Unsafe is now just a delegate for the "real" internal Unsafe, so it is time to move the tests to use it directly. - Cleanup any tests unnecessarily/incorrectly declaring a dependency on sun.misc ( this could have been unnecessarily added, been refactored out at one point, or the library upon which the tests depends refactored, that the dependency is no longer required ). I'm sure further cleanup could be done, but this is sufficient for now. - A small number of test in hotspot/test/compiler/unsafe, which are generated, have been updated, along with the generation script, to depend on jdk.unsupported/sun.misc ( they explicitly test the sun.misc version ) All 'core', 'pit', and 'hotspot' testsets have been successfully run on Mac, Linux, Windows, and Solaris. -Chris.
