Like the error message says, the org.eclipse.core.expressions.Expression class isn't visible. You need to adjust your bundle manifest. If you add that package (or its bundle) to the manifest's imports then it will work.

In the future please use the bug reporting system to report bugs only. If you have a question or need help please use IRC [1] or the Eclipse newsgroups [2].
