[news.eclipse.tools.jdt] Galileo fails after subclipse update

[jeroen.lapre@xxxxxxxxx (jeroen )]

I downloaded galileo and installed it.
The next step is I wanted to install the subclipse plugin:

http://subclipse.tigris.org/update_1.6.x

After completing the minimum update (just the subclipse client and 
dependent), I quite and restart, as recommended by eclipse.

Then I get the error below.

Is this a bug?

thanks
