Hi Szabolcs, The problem is that after a native library is loaded, you can not load a library with the same name. Other Java-based frameworks (e.g. servlets) where packages are restarted or updated without restarting JVM have the same problem. I did not find a way to unload a library on demand such that it can be reloaded again (let me know if you find how to do this). Two (ugly) workarounds for this problem:
1. If you need to load the exact same version of the native library as was already loaded then this exception can be caught and ignored. The actual exception thrown by System.loadLibrary is UnsatisfiedLinkError so you'll have to look at the message text to know if the reason is that the library is already loaded or there is a different problem. 2. Make a copy of your library with a unique name and load it from the copy.
