Sources in first post was updated. Zip contains optimized jBullet lib (thanks EgonOlsen for tips! ), adjusted vecmath lib and sources of PhysicsTest app. On my SGS3 physics calculations of 9 boxes take about 37ms with original libs and 29ms with optimized ones. It is almost 30% speed up, it is not much for my app, but maybe it can help to someone.

Why is the library not loading from the site? JPCT-AE is dead?

no goal))) I'm just doing a great game, and is studying the collision system made this little game.
The purpose of the expense))) Aimless game.
With the way the collision system has not yet figured out whether an object at the same time listen to himself and another object may receive while normal landfill? I have an error in the billiards.

  :-\I realized, it does not work on an emulator Genymotion, running on devices.
