Snippet generator generates this for input step with choice parameters:
input message: '', parameters: [[$class: 'ChoiceParameterDefinition', choices: ['option1', 'option2'], description: '', name: 'My param']]
That code tries to use the @DataboundConstructor of ChoiceParameterDefinition which does not match with the required signature, thus this warning stack trace is shown on snippet generation time:

The generated snippet does not work later on runtime, throwing the same exception.
