Description

If i define methods with same name and parameters on a class, one as static other as instance method, the order becomes important.

Try this in the groovy console:

class IDoNothing {

}

IDoNothing.metaClass.sayHello = {
    println "Instance says hello"
}

IDoNothing.metaClass.static.sayHello = {
    println "Class says hello"
}

def idn = new IDoNothing()

IDoNothing.sayHello()
idn.sayHello()

It will print:
Class says hello
Class says hello
although the second sayHello() was called on an instance. If you define the static method first, all works as expected:

class IDoNothing {

}

IDoNothing.metaClass.static.sayHello = {
    println "Class says hello"
}

IDoNothing.metaClass.sayHello = {
    println "Instance says hello"
}

def idn = new IDoNothing()

IDoNothing.sayHello()
idn.sayHello()

Output:
Class says hello
Instance says hello
