Description

When replaced static method is called from an instance of a class, it still hits original method. Here is code example that fails:

StaticStubFails.java

class Foo {
  static String greet() {
    'Hello from Foo'
   }
}

foo = new Foo()
assert 'Hello from Foo' == foo.greet()
Foo.metaClass.static.greet = { 'Hello from Stub' }
assert 'Hello from Stub' == Foo.greet()

//uncomment line below and it will pass
//foo.metaClass.static.greet = { 'Hello from Stub' }

assert 'Hello from Stub' == foo.greet()
println 'All ok'

Output

assert 'Hello from Stub' == foo.greet()
                         |  |   |
                         |  |   Hello from Foo
                         |  Foo@5e82df6a
                         false
