IllegalStateException from software skinning with zero weights per vertex

[stephengold]

@oxplay2 reported the following crash in SkinningControl (new animation system):

mar 14, 2020 9:56:14 AM com.jme3.app.LegacyApplication handleError
SEVERE: Uncaught exception thrown in Thread[main,5,main]
java.lang.IllegalStateException: Max weights per vert is incorrectly set!

I'm guessing mesh.getMaxNumWeights() returned 0. He says the same scene renders fine with hardware skinning. Perhaps SkinningControl should simply skip over meshes without weights.

Another possibility is that mesh had bone weights but mesh.maxNumWeights wasn't set correctly.

Any progress on this issue so far?

@Scrappers-glitch not that I'm aware of. Note that the issue isn't assigned to anyone.
