Consider the following Java class:

package test22;
public class MyBean {
	private String foo;
	public void setFoo(String foo) {
		this.foo = foo;
	}
}

and the following Groovy class:

package test22
class Test22 {
	public Test22() {
		def b = new MyBean(foo: 'hello')
	}
}

Invoke Call Hierarchy (Ctrl+Alt+H) on MyBean.setFoo(String): the implicit call to that setter triggered by the map-style constructor call in Test22 is not reported.
