I am getting the exact same error.  I have tried Forge2 on every Kepler, Luna, JBoss Dev Studio and I get the error below.  Actually, JBoss Dev Studio will not even let me install Forge2 because Forge1 comes preinstalled and there is no way to uninstall it.  Below is what I get in Kepler and Luna on my Windows machine when I press ctrl + 5.
