CA Automic Workload Automation - Automation Engine


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

U02013310 Failed to load RA Agent.
U00003620 Routine 'UCEX_R' forces trace because of error.
U02000048 TRACE files opened with flag '000000000000001', max.trace: '9', memory trace: '0', search...
U00003449 Output to the TRACE file is finished

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


This was captured on RA Core 11.2.7 and FTP Solution 4.0.8

but can happen with other versions as well.


This error is caused by using an incorrect version of java


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)
