Consider the Groovy class:

package test4
class MyBean {
   String foo
}

and the following:

package test5
class MyBean {
  int bar
}

(please note: two classes with the same name in different packages)
Then the following:

package test5
class TestCompletion {
	void doSomething() {
		new MyB|
	}
}

(please note: same package as the second MyBean class).
Invoke code assist at "|" and choose test4.MyBean(): the constructor invocation is completed, but no import statement is added, hence the class being constructed is indeed test5.MyBean instead of test4.MyBean.
