Description

Consider this Groovy class:

 

package test64

import groovy.transform.CompileDynamic
import groovy.transform.CompileStatic

@CompileStatic
class Test64 {

	@CompileDynamic
	static enum ShippingAddressSynchType {
		ACCOUNTING {
			@Override
			void synch(Test64 customer) {
				truncate('foo', 2)
			}
		};

		void synch(Test64 customer) { }

		private String truncate(String input, int maxLength) {
			if(!input)
				return input
			if(input.length() > maxLength)
				input = input[0..maxLength - 1]
			return input
		}
	}
}

and a Java class to run it:

package test64;

import test64.Test64.ShippingAddressSynchType;

public class Test64Main {

	public static void main(String[] args) {
		Test64 t = new Test64();
		ShippingAddressSynchType.ACCOUNTING.synch(t);
	}
}

If you run this code, you'll get:

Exception in thread "main" groovy.lang.MissingMethodException: No signature of method: test64.Test64$ShippingAddressSynchType$1.truncate() is applicable for argument types: (String, Integer) values: [foo, 2]
