How are unsigned integers being stored in rosjava messages?

It looks like uint32 and uint64 are being stored in the same integers as their signed counterparts: int and long. Can anyone confirm that's the case?

Java doesn't have unsigned integers, so at the very least uint16 should be stored in an 'int' and uint32 should be stored in a 'long', and uint64 should be...???

Looks like this is the case with time as well:
Represented in C++ as uint32_t:
http://docs.ros.org/api/rostime/html/classros_1_1TimeBase.html
And in ROSJava as int: (32 bit signed):
