Type filters are not a satisfying solution for various reasons:

* The user needs to know about them and where to configure it. You
  already lost most of the users with this.
* It doesn't work when your project also needs to use AWT, SWT
  (org.eclipse.swt.widgets.List) or other libraries including a List
  type - you would still have to manually select the correct one.
* There are more cases than java.awt.List.

Here's the bug report for JDT:
