JOC Cockpit: UTF-8 has to be supported when web service writes into database

Current Situation

• Character encoding UTF-8 is not supported by the JOC Cockpit web services when writing into database.
• For example you start a job and type a reason with characters outside Latin-1 then it gets the wrong encoding in the database table AUDIT_LOG.

Desired Behavior

Character encoding UTF-8 has to be supported.

Maintainer Note

Jetty has to be started with Java option -Dfile.encoding=UTF-8
