Trying to extract the text from a power point presentation throws an OutOfMemoryError immediately.  Trying to increase the Heap proved useless.  Trying to create a VM of 2Gigs fails because the VM can't allocate enough space, and anything smaller still provides an OutOfMemoryError.

Here is the following code being executed:

public class Test {
    public static void main(String[] args) throws Exception{
        try {
            PowerPointExtractor _extractor = new PowerPointExtractor(new FileInputStream("Presentation - Spani#113D94.ppt"));
            String _text = _extractor.getText();
            System.out.print(_text);
        } catch( Throwable e ) {
            e.printStacktrace();
            System.out.println( Runtime.getRuntime().freeMemory() + " free out of " + Runtime.getRuntime().totalMemory() );
        }
    }
}
