I believe the way this works is that any jars in the Java directory are added
to classpath _but_ the Java directory itself is not classpath. The Classes
directory it contains is in classpath.
For example:
set java.class.path
java.class.path=/Users/mjh/HalfPipe/HalfPipe7.app/Contents/Java/Classes:/Users/mjh/HalfPipe/HalfPipe7.app/Contents/Java/antlr-2.7.7.jar:…[Other
jars in the Java directory automatically
added].../Users/mjh/HalfPipe/HalfPipe7.app/Contents/Java/weka.jar
Notice Java directory itself not there. Java/Classes is there.
So that you can access resources off of that with something like…
try {
ClassLoader cl = new
java.net.URLClassLoader(new java.net.URL[0]);
BufferedReader rdr = new BufferedReader(new
InputStreamReader(cl.getResourceAsStream("Scripts/loader.js")));
jsEngine.eval(rdr);
}
catch (Exception ex) {
ex.printStackTrace(org.cmdline.common.Configuration.getSysOut()); }
Where Scripts/loader.js is located in the above mentioned Classes directory.
user.dir I would still suggest is not a reliable way to access application
files going forward.

If this provides equivalent functionality and is active this would probably be
the way to go. Given the time, I will look at it. Any handy OS X specific
documentation links would be appreciated.
