Ask for help on new pkg xperia-flashtool on classpath

[Roger Shimizu <rosh@debian.org>]

Dear java and mentors list,

Thanks to ftpmaster's effort and efficiency, my package
xperia-flashtool and all its dependencies all hit unstable lately.
(PS. xperia-flashtool is the open source ROM image flashing tool for
xperia phone.)

However the pkg still cannot be used due to classpath issue, I guess.
After installing xperia-flashtool, and run java command, it report error:

====
$ java -jar /usr/share/xperia-flashtool/x10flasher.jar
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/logging/log4j/core/config/ConfigurationSource
        at gui.Main.run(Unknown Source)
        at gui.Main.main(Unknown Source)
Caused by: java.lang.ClassNotFoundException:

        at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:522)

I tried to add classpath, such as"-cp /usr/share/java/log4j-core.jar",
but all failed.
I guess there's classpath issue either on building, or runtime, or both.
Could anyone kindly help me out?

The git repo locates at:
- https://salsa.debian.org/java-team/xperia-flashtool

Thanks in advance!

Cheers,
