new custom shimeji: ArithmeticException: / by zero

[othello777]

I tried getting the english shimeji showcased in this video https://youtu.be/sHJZWkA-4FA to work on my linux. I used the converter conv.sed for Actions.xml and Behavior.xml and moved the subfolder's images into the img/ directory. I also used the sun java 6 as recommended which is how it worked in the first place. I only get the error after the shimeji has been walking around for a bit. I think the error is tied to a specific pose.
Actions.txt
Behavior.txt
(extension changed only for github upload)

My linux distro: Linux Lite 4.8 amd64 (xfce4)
Run command: /usr/lib/jvm/java6/jdk1.6.0_45/bin/java -classpath Shimeji.jar -Xmx1000m com.group_finity.mascot.Main -Djava.util.logging.config.file=./conf/logging.properties
Error:
