In the case of RCP, it replaces the standard classloader with a new one which tries a series of class load locations and also allows insertion of new locations (as "hooks").  Some of the paths that System.loadLibrary() tries are also determined by this classloader through its findLibrary() method, which is how RCP can use library paths that are not on LD_LIBRARY_PATH.

I assume Sven has done something similar for JOGL's auto extraction and loading.
