This issue is caused by the incompatible library between full version of Hawk 6.2.1 and TRA 5.12. We are working on a fix for this issue.

Please apply the workaround below before we have a fix for this issue:
-. Generate a new encrypted EMS password with tibhawkpassword from cfgmgmt/hawk/bin directory of Hawk 6.2.1, and replace the EMS password for "-ems_transport" in tra/domain/<domainName>/hawkagent.cfg.

For other working machine, please don't install full version of Hawk 6.2.1 in the same TIBCO_HOME of TRA 5.12 till we have a fix for issue. In case features from full version of Hawk is needed, you can install Hawk 6.2.1 in a different TIBCO_HOME.
