I hope I understood your intend. I've tried to replace the recreation of the GraphicsPipeline-Instance by only calling
the native parts. Unfortunately that doesn't seem to work at all. Probably I'm missing some updates.
    public boolean reinit() {
        if (d3dEnabled) {
            if (creator != Thread.currentThread()) {
                throw new IllegalStateException(
                        "This operation is not permitted on the current thread ["
                                + Thread.currentThread().getName() + "]");
            }
            notifyAllResourcesReleased();
            nDispose();
            for (int i = 0; i != factories.length; ++i) {
                factories[i] = null;
            }
            nInit(PrismSettings.class);
            factories = new D3DResourceFactory[nGetAdapterCount()];
        }
        return d3dEnabled;
    }
