Eclipse RCP menu bar
<p>Currently I am working on an update from Eclipse 3 to Eclipse 4. In the new version I have a toolbar on the left, which is only visible in my intro part.</p>

<p>Where does this menubar come from? How can I disable it?</p>

<p>At first I thought it comes from the CustomizableIntroPart, but I have created my own IntroPart and the menu bar still is visible. </p>
