Thanks for the hint!
Below command already shows different a classpath error, so it's moved forward.

$ java -cp /usr/share/xperia-flashtool/x10flasher.jar:/usr/share/java/log4j-core.jar:/usr/share/java/log4j-api.jar
gui.Main

Yes, it set up by build.xml of ant.

So my next question is, how to figure out all the classpath, since
this package really depends on a lot of java libraries.

I tried to set up the classpath automatically by patch, which seems failed:
