The problem was with memory address size. Specifically, calls setUrbAddress/getUrbAddress treat adress as int and only save 32-bit.
In order to fix it, I've had to change the calls to use long and change the signature. Also, I needed to define call CheckedCallLongMethod and use that instead. Everything seems to work now.
