Enum conversion not working: IllegalArgumentException: argument type mismatch for step argument

Summary

Regression between 3.0.2 and 2.4.0 breaks converting enum parameters of steps

Expected Behavior

After reverting to 2.4.0:

> Task :cucumber
Feature: Calculations

  Scenario: Divide              # src/test/resources/calculation.feature:2
Doing Division
    When Division is calculated # CalculationStepdefs.splitInfoPfShiftIsSelected(CalculationType)

1 Scenarios (1 passed)
1 Steps (1 passed)

Current Behavior

> Task :cucumber FAILED
Feature: Calculations

  Scenario: Divide              # src/test/resources/calculation.feature:2
    When Division is calculated # CalculationStepdefs.splitInfoPfShiftIsSelected(CalculationType)

Possible Solution

Steps to Reproduce (for bugs)

src/test/resources/calculation.feature

Feature: Calculations
  Scenario: Divide
    When Division is calculated

package com.example;

import cucumber.api.java.en.When;

public class CalculationStepdefs {

    @When("([\\S]+) is calculated")
    public void splitInfoPfShiftIsSelected(CalculationType calculationType) {
        System.out.println("Doing " + calculationType);
    }
}

package com.example;

public enum CalculationType {
    Multiplication,
    Division
}

build.gradle

plugins { id 'java-library' }

def cucumberVersion = '3.0.2'
dependencies {
    testImplementation "io.cucumber:cucumber-java8:$cucumberVersion"
}

repositories {
    jcenter()
}

task cucumber() {
    dependsOn testClasses
    doLast {
        javaexec {
            main = "cucumber.api.cli.Main"
            classpath = configurations.testRuntimeClasspath + sourceSets.main.output + sourceSets.test.output
            args = ['--plugin', 'pretty', '--glue', 'com.example', 'src/test/resources']
        }
    }
}
build.dependsOn cucumber

Context & Motivation

This blocks me from upgrading to 3.0.2.

The commit with the fix has a descendant tagged with a release version. But it was the release of datatable not cucumber expressions. Hence the confusion.
