Hibernate Configuration launcher file opens Hibernate Console Dialog by default

Steps:
Create Hibernate Console Configuration and store it in as a launcher file in a project. Try to open it. It's opened in a plain text editor.

I would like to see opening via Hibernate Configuration dialog (as similar as when I click on Hibernate Configuration item in Hibernate Console Configuration view).
It have to be recognized according to it's content because filename/extension is general for all launchers (*.launcher).
