--------------------------------------

             Summary: VerifyError when referencing a private enum method
                 Key: GROOVY-9524
                 URL: https://issues.apache.org/jira/browse/GROOVY-9524
             Project: Groovy
          Issue Type: Bug
          Components: Static compilation
    Affects Versions: 2.5.11
            Reporter: Mauro Molinari


Very similar to GROOVY-9523, but here full static compilation is used.

Consider this Groovy class:

{code:groovy}
package test64

import groovy.transform.CompileStatic

@CompileStatic
class Test64 {

        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
                }
        }
}
{code}

and a Java class to run it:

{code:java}
package test64;

import test64.Test64.ShippingAddressSynchType;

public class Test64Main {

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

If you run this code, you'll get:

{noformat}
Exception in thread "main" java.lang.VerifyError: Bad type on operand stack
