Thats true as long as the app only uses a GUI, files, databases, a
printer and network connections. However, this app uses serial ports and
on Windows that requires JNI calls to native code - that's its problem.

Portability requires rewriting the native code, which is typically C or
C++, for each OS. 

The implementation might be slightly more flexible if the Java app used
sockets to talk to a program that translated between a socket and a
serial port, but this program would still need to be ported to new
operating systems. I think socat could be used as the interface on
UNIX-like systems.
