I have tried to add some extending interface to other interface. When i write code: public interface Aaaa extends Clon| { and on the place of | I invoked a CC, there was displayed an empty completion dialog with "Please wait" message. IDE didn't freeze (Esc closed the dialog) but threaddump contained a deadlock. CC cannot be used after this.
