If you google for “Unsupported major.minor version 52.0” you’ll find the answer
to that – you have class files compiled with one Java version (probably some
pre-compiled .jars you got from somewhere), but you are running under a
different Java version ( the class files are probably Java 8, and you are
trying to run using Java 6 or 7).
As far as the deprecated issue is concerned, I can’t comment, sorry.
