This is something that we could clarify in the wiki but after reading the IBM article, you probably understand better... what it written in the Java documentation concerning the direct NIO buffers:

The contents of direct buffers may reside outside of the normal garbage-collected heap

http://docs.oracle.com/javase/7/docs/api/java/nio/ByteBuffer.html#direct

I advise you to evaluate correctly the reliability of a source of information and the most straightforward way to understand how the direct NIO buffers work consists in looking at their implementations.
