My DLL is a message pump that consumes messages by invoking callbacks. My end goal is to have the callbacks be java functions but I am not there yet. Instead, I have the callbacks as C functions in the dll that just print to console. This works fine in a pure c environment. In JNA, I am able to load my dll, but the C callbacks dont work at all. Instead, the DllMain function gets invoked repeatedly.

My questions is, given a message pump scenario, where the C dll has a main loop in a thread that waits for events, would JNA work? Does JNA keep the dll around or is it destroying and reloading it (explaining why DllMain gets called over and over).
