Unsupported major.minor version 52.0 - Error

Hi,



I have gone through the forums and didn't see any posts related to this issue.

I developed a custom web service listener and deployed it on mirth appliance. The jar works perfectly on my local. I am using Java 8 on my local machine. Any guidance is appreciated.



When I deploy the channel I see the following error:



Unsupported major.minor version 52.0
