Check values of math constants to ensure they were not accidently changed

[shadowislord]

Constants like Vector3f.ZERO and others in the math package should be checked each frame (via assertion, or debug option) to ensure they remain what they are supposed to be. This prevents accidental changes by user code.

What about a SanityCheckAppState for this?

[DannyJo]

How about creating an immutable version of the Vectors.

[kwando]

Instance variables in VectorXf is declared public which makes that impossible, without breaking lots of code. =/

[DannyJo]

Oh yes, forgot about that. Back to checking each frame then.

Actually I prepared an Annotation checker for this that can be used in Java6+ during compilation, the code isn't complete but the skeleton is here: https://code.google.com/p/jmonkeyengine/source/browse/#svn%2Fbranches%2Fjme-checker

Thats also why theres the Annotation code in jme3-core
