Hey guys!

So I had some extra time recently and decided to clean up and finally release the official 2.1.2 jbox2d version. Some notes:

* LiquidTest doesn't work as well because of 2.1.2's tree broadphase
* If you want to experiment with your own pooling, feel free to implement IWorldPool and do your worst
* testbed performance isn't as good as previous release, as I'm using java2d instead of processing for compatibility reasons
* The engine seems to be deterministic now, short of using [strictfp] everywhere (which should make it completely deterministic?)
* Should be releasing on maven soon!

I did a decent job of testing this, so hopefully there are no problems, but definitely throw an issue on the issue tracker or shoot me a message if you come across anything. Thanks for all your support!

yee!! yes, it should do the trick!

so now jBOX2D has the same version/capability of the C counterpart?

sorry, but i've downloaded the google's svn (trunk folder) and the code doesn't have "strictfp" anywhere!

And you also should initialize all random() to a number, like random(6).

I'm on the official JBox2d Repository on Google Code and I can't seem to find version 2.1 anywhere!

As I said, we don't put [strictfp] everywhere. That would degrade performance for everyone. If you absolutely need a deterministic engine, you can put [strictfp] in there yourself.

The only 'Random' in there is only used for testing, and does not need to be deterministic, thus it should be fine.
