> --------------------------------------------------
>
> 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
> Assignee: Eric Milles
> Priority: Major
> Fix For: 4.0.0-alpha-3
>
> Time Spent: 0.5h

> 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
> Exception Details:
> Location:
> test64/Test64$ShippingAddressSynchType$1.synch(Ltest64/Test64;)V @1:
> invokevirtual
> Reason:
> Type 'test64/Test64$ShippingAddressSynchType$1' (current frame, stack[0])
> is not assignable to 'groovy/lang/Closure'
> Current Frame:
> bci: @1
> flags: { }
> locals: { 'test64/Test64$ShippingAddressSynchType$1', 'test64/Test64' }
> stack: { 'test64/Test64$ShippingAddressSynchType$1' }
> Bytecode:
> 0x0000000: 2ab6 0036 c000 0412 3805 b800 3c57 b1
