This is the same issue that keeps OpenOffice.org from building with
openjdk-6.

Bug description:
I'm trying to run a custom rhino to build Dojo, but OpenJDK keeps ignoring the rhino in the jar file I provide and keeps loading rhino from the system libs:

$ java -verbose:class -jar ../shrinksafe/custom_rhino.jar
...
[Opened /usr/lib/jvm/java-6-openjdk/jre/lib/rhino.jar]
[Loaded org.mozilla.javascript.tools.shell.Main from /usr/lib/jvm/java-6-openjdk/jre/lib/rhino.jar]
[Loaded org.mozilla.javascript.ContextFactory from /usr/lib/jvm/java-6-openjdk/jre/lib/rhino.jar]
[Loaded org.mozilla.javascript.tools.shell.ShellContextFactory from /usr/lib/jvm/java-6-openjdk/jre/lib/rhino.jar]
...

If I specify a classpath, it still loads from the system rhino library:

$ java -classpath ../shrinksafe/ -verbose:class -jar ../shrinksafe/custom_rhino.jar
...
[Opened /usr/lib/jvm/java-6-openjdk/jre/lib/rhino.jar]
[Loaded org.mozilla.javascript.tools.shell.Main from /usr/lib/jvm/java-6-openjdk/jre/lib/rhino.jar]
[Loaded org.mozilla.javascript.ContextFactory from /usr/lib/jvm/java-6-openjdk/jre/lib/rhino.jar]
[Loaded org.mozilla.javascript.tools.shell.ShellContextFactory from /usr/lib/jvm/java-6-openjdk/jre/lib/rhino.jar]
...

If I change over to using sun's JRE, it works fine:

$ sudo update-java-alternatives --set java-6-sun
$ java -verbose:class -jar ../shrinksafe/custom_rhino.jar
...
