Thanks. We should not rely on this particular directory.

We only define (gluegen-cpptasks-base.xml):

+++

  <target name="setup.java.home.dir.macosx" if="isOSX">
      <!-- Java7 std location -->
      <condition property="java.home.dir"
                 value="${java.home}/..">
                 <available file="${java.home}/../include/jni.h"/>
      </condition>
      <condition property="java.includes.dir"
                 value="${java.home}/../include">
                 <available file="${java.home}/../include/jni.h"/>
      </condition>
      <!-- Fallback value Java6 -->
      <property name="java.home.dir" value="/System/Library/Frameworks/JavaVM.framework/Home" />
      <property name="java.includes.dir" value="/System/Library/Frameworks/JavaVM.framework/Headers" />
  </target>
  ...
      <condition property="java.includes.dir.platform"

      <condition property="java.lib.dir.platform"
                 value="${java.home.dir}/jre/lib">

.. hence if java7 is installed and PATH is set accordingly, i.e.:

JAVA_HOME=`/usr/libexec/java_home -version 1.7`
PATH=$JAVA_HOME/bin:$PATH
export JAVA_HOME PATH

and will use the proper 'java.home' env. var and all shall work.
See e.g. gluegen/make/scripts/make.gluegen.all.macosx-clang.sh (similar script in jogl).

build-nativewindow.xml in jogl only uses:
  <syslibset dir="${java.lib.dir.platform}" libs="jawt" if="@{output.lib.name}.useLibJAWT"/>
