PROPERTY_BUFFER_ALLOCATOR_IMPLEMENTATION set by LwjglContext gets ignored sometimes

Hi

LwjglContext (in jme3-lwjgl3 module) specifies its own implementation of buffer allocator to be used by BufferAllocatorFactory by setting PROPERTY_BUFFER_ALLOCATOR_IMPLEMENTATION property in this static code block:

https://github.com/jMonkeyEngine/jmonkeyengine/blob/8af0c92991eab9c2027dfd94be09f2170beea630/jme3-lwjgl3/src/main/java/com/jme3/system/lwjgl/LwjglContext.java#L91-L102

the issue is that sometimes this property gets ignored by BufferAllocatorFactory and a ReflectionAllocator is created instead. That is because BufferAllocatorFactory.create() method sometimes is called before the LwjglContext sets the new property. Inside the BufferUtils class:

https://github.com/jMonkeyEngine/jmonkeyengine/blob/8af0c92991eab9c2027dfd94be09f2170beea630/jme3-core/src/main/java/com/jme3/util/BufferUtils.java#L65

Sometimes the order of these static executions is different, e.g the one in the BufferUtils runs before the LwjglContext, which will cause BufferAllocator allocator to get initialized with Reflectionallocator and bypass the LWJGL3 allocator.

Edit:
2 possible fixes are suggested for this issue:

and:

Read the static initialization in jme3-core/src/main/java/com/jme3/util/BufferUtils.java and BufferAllocatorFactory.create(), then compare it with the property setup in jme3-lwjgl3/src/main/java/com/jme3/system/lwjgl/LwjglContext.java. Investigate the two proposed fixes linked from issue #1674 and verify that the LWJGL3 allocator is selected regardless of static initialization order.
