The action is located in an Editor toolbar (through an ActionReference) and the tooltip is not showing up when the cursor is on the action icon. Tried multiple variations either implementing ActionListener or extending AbstractAction, without success.
Please clarify how exactly did you register the action. Editor toolbar registrations are done through @EditorActionRegistration, not @ActionReference.
Missing tooltip now showing up using NB7.2 platform. Mark this as fixed.
