GGTS Java Problem

[meeximum]

When working with SpringTool GGTS Eclipse IDE the project is marked as erroneous.
The log says

The inherited method AbstractContainer.addListener(Container.PropertySetChangeListener) cannot hide the public abstract method in Container.PropertySetChangeNotifier DomainItemContainer.groovy /VaadinDemo/.link_to_grails_plugins/vaadin-core-1.0-SNAPSHOT/src/groovy/com/vaadin/grails/data/util line 14 Java Problem

The problem are the Interfaces Container.Filterable, Container.PropertySetChangeNotifier
There are deprecated methods e.g. addListener which are not unique (they exist in multiple interfaces which are implemented) so the compiler doesn't know which do use :-(
