GLRenderer.updateUniform's `assert fb.remaining() == 16` assertion was triggered once, when loading a very large asset on android

[riccardobl]

I have no idea what caused this, or even if it is an issue at all.
Basically I tried to load a very big gltf model on an android 13 device that is not supposed to be capable of rendering it at all, and I've got this assertion triggered during load:

jmonkeyengine/jme3-core/src/main/java/com/jme3/renderer/opengl/GLRenderer.java

Line 1394 in 1f8b5ed

assert fb.remaining() == 16;

afaik OOM or other errors, that are expected in this case, should not meddle with the native buffers position, so this is strange.

I am opening this issue to, just in case, since it might be a race condition that manifests itself only during very heavy loads.

Also: I managed to reproduce this only once.
