The issue is because of Java version mismatch. From the Wikipedia Java Class Reference you can fin all the codes: J2SE 8 = 52,J2SE 7 = 51,J2SE 6.0 = 50,J2SE 5.0 = 49

This error is caused becaused you are using a lower JDK at runtime (probably 7) than 8 that is the one used to compile that version of Jenkins
