Description

Have a simple Gobblin job that is run using gobblin.runtime.embedded.EmbeddedGoblin class. There is a fork in the job followed by converters for each fork. Using converters in fork branches results in below exception - note that there is a converter before the fork and then converters for each branch of fork that have been specified using converter.classes.<fork_number>. If no converters are used in fork branches then this exception is not encountered.

com.typesafe.config.ConfigException$BugOrBroken: In the map, path 'converter.classes' occurs as both the parent object of a value and as a value. Because Map has no defined ordering, this is a broken situation.
