                                          URISyntaxException

Adds native libraries, if not yet added.

Parameters:

certClass - if class is certified, the JarFile entries needs to have the same certificate

jarURI -

nativeLibraryPath - if not null, only extracts native libraries within this path.

Returns:

true if native libraries were added or previously loaded from given jarURI, otherwise false

Throws:

IOException - if the jarURI could not be loaded or a previous load attempt failed
