Description

If a class with static methods is mixed in another class, the static methods are not available as static methods.
Furthermore a strange behaviour occurs - they are available as instance methods and when once called as instance methods they also get available as static methods - see the code below.

class Base {
    def instanceMethod() { println 'instance method' }
    static staticMethod() { println 'static method' }
}

class T1 {}
class T2 {}

T1.mixin Base
T2.mixin Base

t1 = new T1()
t1.instanceMethod()
t1.staticMethod()
T1.staticMethod()   // somehow working, after callling it as an instance method before - thats' strange!!!

t2 = new T2()
t2.instanceMethod()
T2.staticMethod()   // not working: Caught: groovy.lang.MissingMethodException: No signature of method: static T2.staticMethod() is applicable for argument types: () values
