You can use a plugin of JVisualVM to see the native memory usage and look at the direct NIO buffers.

No the direct NIO buffers are correctly cleaned but if you misuse JOGL, it can create direct NIO buffers at each display, for example when you pass an array instead of passing a direct NIO buffer...
