I have trouble getting Logback-Beagle to show in Eclipse 4.3 Kepler

This is the first time I am trying out Logback-Beagle. So I don't know how it should behave.

I followed the instructions on this page: http://logback.qos.ch/beagle/
The installation was successfull. However I can't find the view for Beagle!

I am stuck at the following instruction:

Restarting Eclipse should load the plugin. To access the Beagle View, either type A"lt-Shift-Q, Q" or select: Window > Show view > Other... . You should see the Beagle view nested in the Logback category. Selecting this view will add it to your workspace. It shouls looks as follows:

The instructions and Logback-Beagle plugin works just fine on Eclipse 4.2 Juno! But not on Eclipse 4.3 Kepler

The following jar is installed in X:/eclipse/plugins/ after following the instructions:
ch.qos.logback.beagle_1.1.4.201209042005.jar
