8024176: [macosx] gc/metaspace/ClassMetaspaceSizeInJmapHeap.java failed since jdk8b105, hs25b47 Summary: The code for reading compressed klass pointers in the sa-agent on Mac used readCompOopAddress instead of readCompKlassAddress, this is wrong but has been hidden because compressed oops and compressed klasses has used the same base address in the past.

README:
  This file should be located at the top of the OpenJDK Mercurial root
  repository. A full OpenJDK repository set (forest) should also include
  the following 6 nested repositories:
    "jdk", "hotspot", "langtools", "corba", "jaxws"  and "jaxp".

  The root repository can be obtained with something like:
    hg clone http://hg.openjdk.java.net/jdk8/jdk8 openjdk8
  
  You can run the get_source.sh script located in the root repository to get
  the other needed repositories:
    cd openjdk8 && sh ./get_source.sh

  People unfamiliar with Mercurial should read the first few chapters of
  the Mercurial book: http://hgbook.red-bean.com/read/

  See http://openjdk.java.net/ for more information about OpenJDK.

Simple Build Instructions:
  
  0. Get the necessary system software/packages installed on your system, see
     http://hg.openjdk.java.net/jdk8/jdk8/raw-file/tip/README-builds.html

  1. If you don't have a jdk7u7 or newer jdk, download and install it from
     http://java.sun.com/javase/downloads/index.jsp
     Add the /bin directory of this installation to your PATH environment
     variable.

  2. Configure the build:
       bash ./configure
  
  3. Build the OpenJDK:
       make all
     The resulting JDK image should be found in build/*/images/j2sdk-image

where make is GNU make 3.81 or newer, /usr/bin/make on Linux usually
is 3.81 or newer. Note that on Solaris, GNU make is called "gmake".
