      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]
