This is the expected behaviour: OverCASE requires JRE 1.8 (or newer). Java 7 uses major version 51 (and is, therefore, unable to cope with .class files compiled for Java 8). Java 8 uses major version 52 (which is what we're seeing here).
To run OverCASE on a given machine I recommend this Java distribution: https://adoptopenjdk.net/?variant=openjdk8&jvmVariant=hotspot
This is the open-source fork of Oracle JDK/JRE 8 which does not require a paid licence for personal or commercial use.
Hoping this helps,
