This is an other fork of jbullet, the fork includes :

• jbullet 20101010-1 a port of bullet 2.72 (a physics engine) minus some features
• the Spring Constraint (Generic6DofSpringConstraint) from https://github.com/affogato/JBullet-QIntBio-Fork
• the modification from jmonkeyengine team (see commits)
• a relayout of the project to build with gradle, demo (code + dependencies) moves under test
• the Spring Constraint for jme-jbullet
• remove some useless code (useless variables), detected by eclipse'analyzer
• fix a swap in HashedOverlappingPairCache.findPair see code above comment

The goal of the fork in to be used with jmonkey-engine (may be when bullet-native can't be used).
