Simply generating the getter, setter, equals and hashcode is only part
of the problem. There also need to be a way to enumerate/loop over the
properties. Without this, each framework will continue to write their
own "bean introspector".

My work in this area is Joda-Beans, http://joda-beans.sourceforge.net/
which uses simple but effective repetitive code generation (ie. not
one-off code generation). I'd love to have someone join the project
and write an Eclipse plugin to regenerate within the IDE and hide/fold
the auto-generated code. There is also an opportunity for someone to
add invoke dynamic for a Java 7 specific version.

Part of the purpose of Joda-Beans is to test out an API and design for
properties. Being used in OpenGamma http://developers.opengamma.com/
(a large open source stack for finance) is the perfect test.
