Problem solved! You just need to make your buffers native ordered. To do so, change:

// vertexPositions = ByteBuffer.allocateDirect(verticesSizeInBytes).asFloatBuffer();
                vertexPositions = Buffers.newDirectFloatBuffer(verticesSize);

and

// indices = ByteBuffer.allocateDirect(indicesSizeInBytes).asShortBuffer();
                indices = Buffers.newDirectShortBuffer(indicesSize);

When I make those two changes, I see two white squares on screen
