>                 Key: GROOVY-10922
>                 URL: https://issues.apache.org/jira/browse/GROOVY-10922
>             Project: Groovy
>          Issue Type: Bug
>          Components: Compiler, Static compilation
>    Affects Versions: 2.5.19, 3.0.14, 2.5.20, 2.5.21
>            Reporter: Jason Garrett
>            Assignee: Eric Milles
>            Priority: Major
>              Labels: StackOverflowError
>
> In the following situation, under static compilation:
>  * An interface declares a getter and/or setter
>  * An implementing class declares a property of the corresponding name and type, so the implicit getter and/or setter implement the interface
>  * A subclass overrides the getter/setter and calls the super getter/setter
> the subclass getter/setter will recurse instead of calling the superclass implicit method.
> This appears to have been introduced in 3.0.14.
> Running the main method in this example will reproduce the stack overflow.
> {code:java}
> package example
> import groovy.transform.CompileStatic
> @CompileStatic
> class SuperImplicitSetter {
>    interface FooHaving {
>       String getFoo()
>       void setFoo(String foo)
>    }
>    static class Foo implements FooHaving {
>       String foo  // implements interface
>    }
>    static class Bar extends Foo {
>       String bar
>       @Override
>       void setFoo(String foo) {
>          super.setFoo(foo)  // recurses instead of calling implicit Foo.setFoo(String)
>          bar = foo
>       }
>    }
>    static void main(String[] args) {
>       Bar bar = new Bar()
>       bar.setFoo("bar")  // stack overflow
>       println bar.foo
>    }
> }
>  {code}
