The problem comes from encoding an EnrichmentFailures bad row on this line
This type of bad row contains an EnrichmentPayload with a RawEvent and this RawEvent contains a DateTime
But encoding this DateTime fails because of NoClassDefFoundError. Could not initialize class org.joda.time.format.ISODateTimeFormat$Constants
I suspect that enrich brings another version of joda.time than the one from snowplow-badrows
