Jonathan Cottrill created GROOVY-8587:
-----------------------------------------
Summary: Calling super in an overridden method results in
MissingMethodException when method indirectly inherited from trait
Key: GROOVY-8587
URL: https://issues.apache.org/jira/browse/GROOVY-8587
Project: Groovy
Issue Type: Bug
Affects Versions: 2.4.15
Reporter: Jonathan Cottrill
Consider the following:
{{trait A {}}
{{ void doSomething() {}}
{{ println "A"}}
{{ }}}
{{}}}{{trait B extends A {}}}{{class C implements B {}}
{{ @Override}}
{{ void doSomething() {}}
{{ B.super.doSomething()}}
{{ }}}{{static void main(String[] args) {}}
{{ new C().doSomething()}}
{{ }}}
{{}}}
Although this compiles fine, a MissingMethodException is thrown at runtime:
{{Exception in thread "main" groovy.lang.MissingMethodException: No signature
of method: static B.doSomething() is applicable for argument types: (C) values:
[C@12f41634]}}
