The per-worker _new_refs array is used to hold references that point into the collection set. It is populated during RSet updating and subsequently processed. In the event of an evacuation failure it processed again to recreate the RSets of regions in the collection set. Remove the per-worker _new_refs array by processing the references directly. Use a DirtyCardQueue to hold the cards containing the references so that the RSets of regions in the collection set can be recreated when handling an evacuation failure.

README:
This file should be located at the top of the OpenJDK Mercurial repository
forest. This top or enclosing repository will include a "make" directory,
and a Makefile at the very top of the repository.
It should also include the 6 repositories: "jdk", "hotspot", "langtools",
"corba", "jaxws" and "jaxp".
See http://openjdk.java.net/ for more information about the OpenJDK.
Simple Build Instructions:
1. Download and install a JDK 6 from
http://java.sun.com/javase/downloads/index.jsp
Set the environment variable ALT_BOOTDIR to the location of this JDK 6.
2. Download and install the Binary Plugs for the most recent JDK7 from
http://download.java.net/openjdk/jdk7/
Set the environment variable ALT_BINARY_PLUGS_PATH to the location of
these binary plugs.
3. Check the sanity of doing a build with the current machine:
gnumake sanity
See README-builds.html if you run into problems.
4. Do a complete build of the jdk:
gnumake all
The resulting JDK image should be found in build/*/j2sdk-image
where gnumake is GNU make 3.78.1 or newer, /usr/bin/make on Linux and
/usr/sfw/bin/gmake or /opt/sfw/bin/gmake on Solaris.
