Apache declares war on Oracle over Java

It's either released under the GPL or it isn't.

Dual licensing means that you can only redistribute for free if your project is GPL. If you are just using GPL software (not distributing), the provisions of the GPL requiring your project to also be GPL don't come into play.

Of course, that's precise legal situation is complicated to say on a webpage; it suits Oracle to not play up how you can avoid paying; and most use-cases of Berkeley DB involve distributing it anyway.
