Building a smaller distribution.

We're looking to use PDFBox in an applet; however, its large size isn't
appealing. We don't need many of the features or languages, so we're
thinking of building it with only what we need.

Any pointers on what to remove?

something something." They are focusing on machines. But in fact we need to
focus on humans, on how humans care about doing programming or operating the
application of the machines. We are the masters. They are the slaves. --

I suggest the PDFBox team releases a light version for its jar.
I see a package inside the new PDFBox jar for version 1.2.1 with the path 'com.ibm.icu' ... I wonder what's that for !

Best regards ,

We call here jar stripper, lol. 
But this one we´ve made ourselves and it is very specific for our situation.
However, basically you have to add a premain to your app and through
instrumentation you get the loaded classes:

public static void premain(final String agentArguments, final
Instrumentation instrumentation) {
		Runtime.getRuntime().addShutdownHook(new Thread() {
			@Override
			public void run() {
				Class<?>[] allLoadedClasses =
instrumentation.getAllLoadedClasses();
	                  // here you can work with your array as you wish.
Getting names or whatever.
			}
		});
	}

You might want to build your applet first.
Then, create (probably there is some on the internet) a little app to see
what classes the classloader used.
Build your jar based on this information.
