问题
We are using dropwizard version 0.6.3. When we try to upgrade version 0.7.0, we are getting this error on service start.
Exception in thread "main" java.lang.VerifyError: class com.fasterxml.jackson.module.afterburner.deser.SuperSonicBeanDeserializer overrides final method deserialize.(Lcom/fasterxml/jackson/core/JsonParser;Lcom/fasterxml/jackson/databind/DeserializationContext;)Ljava/lang/Object;
Tried searching, didn't get any solution. When i looked into SuperSonicBeanDeserializer class, it has one override method. But the class SuperSonicBeanDeserializer is final. I'm not sure how to resolve this problem. Any solution/suggestion, will help us lot.

A look at the maven dependency tree should help find where the problem is:
mvn dependency:tree -Dverbose
Look for "omitted for conflict" within the results. You likely have a version of jackson-databind older than 2.3.0 that is overriding the version in Dropwizard 0.7.
