Not that I'm aware of. LGPL is a less restrictive license and I started out using it instead of BSD and primarily because JavaRelational is an older project and I just never changed the license.

JavaRelational is pretty stable in its current state, but when I get some free time I have some ideas about doing a complete rewrite that will provide a lot of new features. If you end up using JavaRelational or a project let me know how you like it and any criticism is welcome.
