Deallocating Direct Buffer Native Memory in Java for JOGL

Question

I am using direct buffers (java.nio) to store vertex information for JOGL. These buffers are large, and they are replaced several times during the application life. The memo

Answer 1

Direct buffers are tricky and don't have the usual garbage collection guarantees - see for more detail: http://docs.oracle.com/javase/7/docs/api/java/nio/ByteBuffer.html#direct

If you are having issues, I'd suggest allocating once and re-using the buffer rather than allocating and deallocating repeatedly.
