      I'm working on implementing a new step in a plugin, and came across the following error:
      If one argument step is a Map, and it is a field annotated with @DataBoundSetter, Ok, no problems. But if it is a Setter annotated with @DataBoundSetter the following error occurs during instantiation:

      Apparently the error is in injectSetters() method of the class DescribableHelper
