Description

List liste = new ObservableList<String>()

liste.add "test"
liste.add "test2"

List andereListe = new LinkedList<String>()

liste.retainAll

{ elem -> andereListe.contains(elem) }

assert liste.isEmpty()
____________________________________________

This results in:
____________________________________________
Exception in thread "main" Assertion failed:

assert liste.isEmpty()

false [test] ____________________________________________

If the ObservableList is changed to LinkedList, the testcase works.
