                        throws IOException

Force native-lib-loader to first look in the location defined as bootPath prior to extracting a native library, useful for sandboxed environments. NativeLoader.setJniExtractor(new DefaultJniExtractorStub(null, "/opt/nativelibs"))); NativeLoader.loadLibrary("mylibrary");
