Hi John,

I'm seeing if I can get it to build on 10.6.8.

I'm using my recent build of jdk7u-dev build for ALT_BOOTDIR and ALT_JDK_IMPORT_PATH.

  $ /usr/libexec/java_home --version 1.7 -V

  Matching Java Virtual Machines (1):
    1.7.0_04, x86_64: "OpenJDK 7" ~/Library/Java/JavaVirtualMachines/1.7.0_04.jdk/Contents/Home

I cloned the forest http://hg.openjdk.java.net/jdk8/tl/ into sources

Regarding step 3: Add Michael's patches to jdk.  (Crucial!)

For the time being you have already added this patch to the mlvm patch set as:  'macosx-7113349.patch' right?

I've set the guards to: "buildable testable"

I added a .rvmrc file in the main dir to make sure the Ruby 1.8.7 is selected (needed to build jobjc).

I'm getting an unknown revision error trying to patch hotspot:

    *** running: hg update -r
 
  + (cd sources/.; hg update -r $(sh $davinci/patches/make/current-release.sh))
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  + (cd sources/hotspot; hg update -r $(sh $davinci/patches/make/current-release.sh))
  abort: unknown revision 'b279f99d7143'!

Were you basing this on the jdk8/tl forest?
