Wrong syntax highlighting when a method parameter named "owner" is referenced within the body of a closure used inside that method

Consider the following interface:

package test;

public interface I
{
	String getProp();
}

and the following Groovy class:

package test

class A {
	String myMethod(I owner) {
		doNothing { return owner.prop }
	}

	Object doNothing(Closure<Object> c) {
		return c.call()
	}
}

Look at the body of myMethod. The prop property of owner is underlined because at that point owner is not recognized as the "owner" method parameter of myMethod: the parser seems to think it's the owner of the closure, although the "mark occurences" and the "go to declaration" features work correctly.
