I could resolve my problem by decreasing version of Spark Framework that I was using Earlier i was using Spark Framework version : 2.0.0 Degraded version to 1.1.1 And it worked. Hope other people will find it useful. – Cantrip

Increasing the jdk/jre version it uses would also work. – Betaine

In my case had multiple jdks, so just needed to set JAVA_HOME to 1.8 – Lareine

Answer 1

You are using Java files, compiled with Java 8 (version 52.0) and a JRE which does not support it (so Java < version 8)
