[Bug report] TerrainQuad overlapping with Ghost

I’m throwing a Ghost controller to a solid TerrainQuad and I want to detect the collision when it actually hit the ground.

But instead, it looks like the TerrainQuad is overlapped when the Ghost overlaps the TerrainQuad’s bounding box.

Try this:

When you click the mouse, you should get instantly get the collision, unless you are at the top of the highest mountain…

I’ve tested with jBullet and native Bullet.

The documentation samples uses ray casting for checking collision and are unaffected by this bug.

Could somebody please have a look on this?

Is this a known behaviour?
