On Mac's the location will change between different versions.  You are also
supposed to be able to set preferences that determine which Java gets
executed when you have multiple versions installed.

I was going to install this code, but it would be nice if someone with a
Mac could verify that it actually works.

  # On Mac OS X 10.5 and following, run /usr/libexec/java_home to get
  # the value of JAVA_HOME to use.
  # (http://developer.apple.com/library/mac/#qa/qa2001/qa1170.html).
  JAVA_HOME=`/usr/libexec/java_home 2>/dev/null`
