Issue/Introduction

When starting RA FTP agent in Automic Workload Automation, the agent ends immediately.  Logs show:

U02013310 Failed to load RA Agent.

A forced trace file is created in the agent's /temp directory and in looking at the forced trace file, see the following error:

20200603/081321.923 - 17     ----------------------- Stack Trace -----------------------
20200603/081321.924 - 17     java.lang.UnsupportedClassVersionError: com/uc4/ftpjob/connections/ConnectionManager : Unsupported major.minor version 52.0

Environment

This was captured on RA Core 11.2.7 and FTP Solution 4.0.8

but can happen with other versions as well.

Cause

This error is caused by using an incorrect version of java

Resolution

Be sure to use java 8 or higher.  The easiest way to test that the correct java is used is to find the full path to the jre/bin directory and update the start command to include:

(full path to jre)/bin/java -jar (rest of start command here)
