RPI Problems....perhaps Java failure?

Hi Modesfan and the crew,
perhaps you can help with this problem?
After sharing 24/7 on Windows, since 3 days i got no connection to the database, i decided to stream data on the RPI.
I installed "modesfiltered", did the necessary setting in "variables.txt", "modes.sh" was copied to "etc/init.d" as described, but when i'm checking the output log, i got this message:
pi@raspradar:~/modesfiltered $ cat /var/log/modes.log
Exception in thread "main" java.lang.UnsupportedClassVersionError: modesproject/Logging_ModeS : Unsupported major.minor version 52.0

Any idea? Perhaps there is a Java failure?
I'm not the RPI/Linux expert, i can copy files, make it executeable, start, stop and show the status.... that's it, unfortunately!
