rxtx-rebundled is a slightly modified version of the original
rxtx 2.1-7r2. The only difference is:
1) It's a working mavenized library
2) There's just one JAR required. Nothing else. The native libs are bundled
with the jar-file.
3) You don't have to care about "java.library.path". This version will on
startup extract the correct native libs to system temp folder and loads them
automatically. When JVM terminates, temp files will be removed.
