> 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$1' }
>   Bytecode:
>     0x0000000: 2ab6 0036 c000 0412 3805 b800 3c57 b1  
>         at test64.Test64$ShippingAddressSynchType.<clinit>(Test64.groovy)
>         at test64.Test64Main.main(Test64Main.java:9)
> {noformat}
