> JEXL displays an erroneous "inaccessible or unknown property" warning when you try to
access a property is both accessible, and known, but that happens to return null.
> Consider the following code:
> ---
> 	public void testInaccessibleProperty()
> 		throws Exception {
> 		JexlEngine engine = new JexlEngine();
> 		JexlContext context = new MapContext();
> 		context.set( "foo", new Foo() );
> 		// These lines okay
> 		System.out.println( engine.createExpression( "foo" ).evaluate( context ));
> 		System.out.println( engine.createExpression( "foo.baz" ).evaluate( context ));
> 		// This line says:
> 		// org.apache.commons.jexl2.Interpreter unknownVariable
> 		// WARNING: org.metawidget.example.swing.appframework.JexlTest.testInaccessibleProperty@44![0,7]:
'foo.bar;' inaccessible or unknown property foo
> 		System.out.println( engine.createExpression( "foo.bar" ).evaluate( context ));
> 	}
> 	public class Foo {
> 		public String getBar() {
> 			return null;
> 		}
> 		public String getBaz() {
> 			return "baz";
> 		}
> 	}
