problem when field and method with same name

I'm
evaluating JRuby to generate PDFs with iText
(http://www.lowagie.com/iText/) and trying to translate the java
helloworld at http://itextdocs.lowagie.com/examples/com/lowagie/examples/general/HelloWorld.java
to jruby.

I got stuck at step 3:

document.open();

The API documentation shows that the Document instance has both a
field and method named open
(http://itextdocs.lowagie.com/docs/com/lowagie/text/Document.html )
and when I call document.open in jruby, I always get false returned.

Solution, from Charles: do not provide the shortcut property-style accessors when they shadow a real method.
