> If a method parameter's default value is defined by concatenating a String
> literal to a String variable, calling the method throws
> java.lang.NoSuchMethodError.
> {code:java}
> import groovy.transform.CompileStatic
> import spock.lang.Specification
> @CompileStatic // works without CompileStatic
> class MyClass {
> String makePlural(String word, String plural = word + "s") { //
> java.lang.NoSuchMethodError: 'java.lang.String
> java.lang.String.plus(java.lang.CharSequence)'
> return plural
> }
> }
> class Test extends Specification {
> def test() {
> setup:
