You might check to verify that your objects are not being GC'd (JNA native code prints to stderr if a callback has been GC'd, but in the case of a service, that likely just goes nowhere). You can do this by adding a printf to the object's finalize method, or creating a WeakReference with an associated ReferenceQueue.

I'll check, but I already have a static reference to the callback objects.

Yes, but if your class itself is GC'd, those static references will go away. See if you can get a thread dump to see what the VM is doing. You may need to spawn a sleeping thread whose sole function is to keep a reference to your objects.
