You means using 'Buffers.newDirectByteBuffer(bytes)' instead of 'ByteBuffer.wrap(bytes)' ?

I mean that you should create a direct NIO buffer with Buffers.newDirectByteBuffer() only once and reuse it. As you don't show a complete example, I don't really know what you do. If you create a new buffer at each call of GLEventListener.display(), you'll run out of memory.
