Unsupported major.minor version 51.0

Error:

When dropping my .class file within the customClasses directory and restart Adeptia, the Global Methods within the data mapper disappear

 

I receive this error within the WebRunner Application log:

java.lang.UnsupportedClassVersionError ..... Unsupported major.minor version 51.0

 

Cause:

This means that you compiled your classes under a specific JDK, but then try to run them under older version of JDK.

 

Solution:

Compile the class under an older version of Java
