Hi Andrey, thanks for your reply.
The class is on the jar created with `*sbt assembly*` that is submitted to
Flink to start a Job.
unzip -l target/jar/myapp-0.0.1-SNAPSHOT.jar | grep DateTimeParserBucket
1649 05-27-2016 10:24
org/joda/time/format/DateTimeParserBucket$SavedField.class
1984 05-27-2016 10:24
org/joda/time/format/DateTimeParserBucket$SavedState.class
8651 05-27-2016 10:24
org/joda/time/format/DateTimeParserBucket.class
Shouldn't this be enough ?
I think it uses is when nothing happens, but as soon it have some
exceptions, looks like it "forgets" it.
Like I said before, this is kind of intermittent.
Thanks,
David
