Jberet transaction problem

My environment:

• Java 11.0.4
• Wildfly 20.0.1.Final
• Jberet 1.3.4.Final
• job persistence on postgres

Today in a test environment a a job does not start up as usual.

After investigation on job_execution table, job status is STARTING, but no start_time i s set, see image:

Looking in wildfly's server.log reveal following error:
