@tmjchu - it seems more likely that you are using an old version of jackson-annotations jar with a new version of jackson-databind jar. Try using matching versions, eg 2.15.0 for all jackson-* jars.

@tmjchu As per @pjfanning error comes from old version of jackson-annotations or such -- version incompatibility across different Jackson components. This is one reason to use jackson-bom for getting consistent set of dependencies.
