Eric Milles updated GROOVY-10380:
---------------------------------
Fix Version/s: 3.0.20
> SC: IncompatibleClassChangeError when calling interface default method from
> non-public interface
> ------------------------------------------------------------------------------------------------
>
> Key: GROOVY-10380
> URL: https://issues.apache.org/jira/browse/GROOVY-10380
> Project: Groovy
> Issue Type: Bug
> Components: Static compilation
> Reporter: Eric Milles
> Assignee: Eric Milles
> Priority: Major
> Labels: default-methods
> Fix For: 4.0.0-rc-1, 3.0.20
>
>
> Consider the following:
> {code:java}
> package p;
> interface I {
> default void m() {
> System.out.println("works");
> }
> }
> public abstract class A implements I { // or concrete or implemented in groovy
> }
> {code}
> {code:groovy}
> // not in package p
> @groovy.transform.CompileStatic // works if CompileDynamic or TypeChecked
> class C extends p.A {
> void test() {
> m() // IncompatibleClassChangeError: Found class C, but interface was
> expected
> }
> }
> {code}
> In the case of a non-public interface with a public default method, static
> compilation produces a runtime error that is not present for dynamic groovy
> or java.
