Description

Consider the following:

import groovy.transform.NamedParam
import groovy.transform.NamedParams

@groovy.transform.TypeChecked
//@Configuration
class Config {
  //@Value
  String indexName
  //@Bean
  ResultType resultType() {  }
  //@Bean
  def facetApplier() { new FacetApplier(index:indexName, resultType:resultType()) }
}
//@Component
class FacetApplier {
    protected final String index
    protected final ResultType resultType

    FacetApplier(@NamedParams([
        @NamedParam(value='index', type=String, required=true),
        @NamedParam(value='resultType', type=ResultType, required=true)]) Map props)
    {
        this.index = props.index
        this.resultType = props.resultType
    }
}
class ResultType {
}

Constructor call expression "new FacetApplier(index:indexName, resultType:resultType())" has static type checking error for "resultType" named parameter. [Static type checking] - parameter for named arg 'resultType' has type 'java.lang.Object' but expected 'ResultType'.

If resultType() is cast or replaced with a variable, the error goes away.
