#1 : JDK 8.0 Compatibility with highcharts-export-server

When we use JDK 8.0, it produces an error (very difficult to understand) with a java.lang.IllegalArgumentException.

The test was done on JDK 1.7.55 and JDK 1.8.20 and both are oks !

It's due to spring-version and cglib version which is too old (cglib was removed because it's not necessary anymore !).
