Paul King updated GROOVY-7362:
------------------------------
Fix Version/s: (was: 2.5.3)
> Can't compile Java class extending Groovy abstract class with explicit
> GroovyObject interface
> ---------------------------------------------------------------------------------------------
>
> Key: GROOVY-7362
> URL: https://issues.apache.org/jira/browse/GROOVY-7362
> Project: Groovy
> Issue Type: Bug
> Components: Compiler
> Affects Versions: 2.4.0
> Reporter: Peter Gromov
> Assignee: Paul King
> Priority: Major
> Fix For: 3.0.0-alpha-4
>
>
> That's a more advanced version of GROOVY-3877
> Compile classes.groovy:
> {code}
> abstract class AbstractClass extends ConcreteClass implements GroovyObject {}
> class ConcreteClass {}
> {code}
> Then compile JavaClass.java:
> {code}
> public class JavaClass extends AbstractClass {}
> {code}
> You get:
> {quote}
> JavaClass.java:1: error: JavaClass is not abstract and does not override
> abstract method setMetaClass(MetaClass) in GroovyObject
> public class JavaClass extends AbstractClass {
> ^
> 1 error
> {quote}
> That's likely because setMetaClass is added as a synthetic method in
> ConcreteClass and not overridden in AbstractClass.
> This also happens without explicit GroovyObject interface when using joint
> compilation
> (https://youtrack.jetbrains.com/issue/IDEA-137722#comment=27-952814). Before
> generating stubs, "implements GroovyObject" is added to Groovy classes, and
> if it so happens that AbstractClass is visited before ConcreteClass, then
> "implements GroovyObject" will be added to both Groovy classes, but the
> (synthetic) implementations somehow end up being only in ConcreteClass.
