[GROOVY-6888] Static type checking fails if I change the closure input parameter name

Description

Consider the following:

@TypeChecked
class A {
  @Bindable
  String foo
  
  static void main(String[] args) {
	  A a = new A()
	  a.foo = 'old'
	  a.addPropertyChangeListener('foo') { event ->
		  println 'foo changed: ' + event.oldValue + ' -> ' + event.newValue
	  }
	  a.foo = 'new'
  }
}

The Groovy compiler fails:

[Static type checking] - No such property: oldValue for class: java.lang.Object

This is unexpected, because if I leave the event naming of the closure input parameter and use it.oldValue/it.newValue the static type checking succeeds (as it should).
