I hope there's still someone around this topic, cause I've a memory issue with JBullet.
It seems to generate a lot of " int " when calling DynamicWorld.stepSimulation.
I did profile the software using the JVisualMachine, it seems the memory leak is comming from com.bulletphysics.utils.Stacklist.<init>
I have no idea what is going on, the but garbage collector is running every 5 or 6 seconds to clean the mess, which cause my 3D app to freeze for half a second every 5 or 6 seconds.
Any idea ?
