OS X JRE 7u6-ea now on java.net

[Jeff Palmer]

Will do.  Was planning to add Lion in a partition left over from a Ubuntu
experiment a while back anyway.  All kinds of errors from DiskUtility trying
to get rid of it.  Cannot put it off any longer, even if a bare metal
rebuild required.

On the JNLP front, if this is not going possible on Snow Leopard need to
forgo all Java 7 enhancements.  Also need to construct a JNLP to reflect
this.  This is close to what I have now, which works:

  <resources>
      <j2se 
          version="1.7"
          java-vm-args="-Xmx200m -Dswing.grayrect.color=Transparent
-Djava2d.speedofpainting=UNIMAGINABLE"
      />
      <jar href="my-app.jar" main="true" size="1632651" />
  </resources>

  <resources os="Mac">
      <j2se 
          version="1.6"
          java-vm-args="-Xmx200m -Dswing.grayrect.color=Transparent
-Dapple.awt.graphics.UseQuartz=true"
      />
  </resources>

I cannot figure out to segregate Java version for a specific version of an
OS.  I absolutely will NOT support Java 6 on Windows or Linux.  The JNLP was
my enforcement vehicle.  How can this be done?
