Build Tranquilizer from Tranquility example get Jacson java.lang.VerifyError

Try to reproduce https://github.com/druid-io/tranquility/blob/master/core/src/test/java/com/metamx/tranquility/example/JavaExample.java and get exception:

Exception in thread “main” java.lang.VerifyError: class com.fasterxml.jackson.module.scala.ser.ScalaIteratorSerializer overrides final method withResolved.(Lcom/fasterxml/jackson/databind/BeanProperty;Lcom/fasterxml/jackson/databind/jsontype/TypeSerializer;Lcom/fasterxml/jackson/databind/JsonSerializer;)Lcom/fasterxml/jackson/databind/ser/std/AsArraySerializerBase;

on line:

final Tranquilizer<Map<String, Object>> sender = DruidBeams.fromConfig(wikipediaConfig).buildTranquilizer(wikipediaConfig.tranquilizerBuilder());

My pom only include core tranquility dependency:

        <dependency>

io.druid
tranquility-core_2.11
0.8.0

As I understand it is a common issue (https://github.com/FasterXML/jackson-module-scala/issues/214
), but i cannot resolve it. May by some one know workaround of this issue?

Hey Никита,

Could you please share your pom and source code? Perhaps in a public github repository or zip file.
