Bullet Memory Leak

I do not speak very well in English. I found a memory leak when using Bullet. Everything is carefully checked - this is the problem. Memory increases to one and a half gigabytes, and the vvvv breaks with an error Null Pointer Exception. Can you tell me something like solution?

If you turn off “ApplyForce” and “ApplyImpulse”, half the problem is solved - the memory is not increased.
