detach it.
+If you ever want to use JNI in a native thread (created by "SDL_CreateThread()"),
+it won't be able to find your java class and method because of the java class loader
+which is different for native threads, than for java threads (eg your "main()").
+
+the work-around is to find class/method, in you "main()" thread, and to use them
+in your native thread.
