I downloaded the source code from
and found this little bat file called run-jiuawt.bat containing a single line:
java -mx300m -jar jiu.jar
I did a
/usr/bin/find . -name \*.java | xargs grep -in main
and found a a dozen main programs!
Which main program am I running when I run run-jiuawt.bat?

Open MANIFEST.MF file in the META-INF folder in a text editor. The Main-class entry should let you know.

As Stephan says, there is a META-INF/MANIFEST.MF file inside the JAR file that specifies what the main class is.
