Description
Running the TestQ3 application with jme3-jbullet, I've noticed a slight vertical vibration of the camera, apparently caused by unexpected motion of the PhysicsCharacter. The amplitude appears to be position-dependent and is often large enough to disable jumping.
I've seen this in "master" and "v3.4" branches and also in "v3.3" with jme3-jbullet. It doesn't occur with Minie, nor does it occur in the "v3.2" branch with jme3-jbullet.
Could this be related to https://hub.jmonkeyengine.org/t/bettercharactercontrol-jumping-on-plain-surface ?

Research direction
Reproduce the vertical camera vibration in the TestQ3 application with jme3-jbullet, comparing the v3.2, v3.3, v3.4, and master branches and the Minie backend. Start by tracing the PhysicsCharacter motion during jumping and compare it with the linked BetterCharacterControl discussion. Done means the vibration is eliminated and jumping works normally without regressing the unaffected configurations.
