Jonathan Cottrill updated GROOVY-8587:
--------------------------------------
Description:
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]}}
