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

Description

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.

Please note that also the code assist is wrong just like the highlighting: if you try to invoke code assist at owner.| at that line, the "prop" property is not proposed.

The inferencing engine is inferring the wrong owner. It is thinking it is coming from the closure, not as a parameter.

Partial fix implemented for both owner and delegate. Working as expected for single closures, but not for nested closures. Eg-

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

The reference to owner is incorrectly inferred to be Closure, which is correct if there were no owner parameter.
