Bootstrapping with Apple's JDK 6 on Snow Leopard

[Michael Franz]

Kent,

I did some experimenting with this process.  I was able to build OpenJDK
using Apple's JDK and an older version of OpenJDK7.  The older version you
can get from here http://landonf.bikemonkey.org/2008/08/index.html

The process that I followed is based on the same process you used.  Where it
is different is that I created a script to create a standard JDK layout
using Apple's JDK 1.6, applied small patches to langtools.  The older JDK is
used only to run GenStubs.  Where ever you install this JDK change the entry
I created in langtools/make/build.properties  'alt.java.home'.

Once this built, I used it to build the JDK again (I used two different
repos for this).  I built it a second time so that I was not running any of
my patches - as they are only needed to work around limitation in Apple's
JDK.

Hope this works for you.

Michael
