-	 * We fail silently here because (it seems) <em>expected</em> exceptions occur
-	 * more frequently than intermittent <em>unexpected</em> exceptions that might
-	 * merit investigation (and a logged stacktrace might be the only hint as
-	 * to what happened).
-	 * <p>
-	 * We will get an <em>expected</em> exception (typically a {@link NullPointerException NPE})
-	 * here if the user:<ol>
-	 * <li>modifies the Java source file in a way that puts it drastically out
-	 *     of sync with the Dali context model (e.g. deleting a field or
-	 *     annotation)
-	 * <li>immediately invokes Content Assist (typically <code>Ctrl+Space</code>)
-	 * </ol>
-	 * The AST we build here will be based on the just-modified Java source; but,
-	 * since the user moved quickly and we will not have yet received any Java
-	 * change notification (since we only get a Java change notification when
-	 * the user has paused typing for at least 0.5 seconds), the context model
-	 * will still be based on the unmodified Java source. As the new AST is
-	 * passed down through the context model to the resource model all the code
-	 * expects to find the AST in sync with the model. When this is not the
-	 * case (e.g. a field in the resource model is no longer present in the AST
-	 * because the user has deleted it or modified the code in such a way that
-	 * the parser can no longer detect the field) the model will probably choke
-	 * when it cannot find the corresponding AST node.
-	 * <p>
-	 * It seems reasonable, in these situations, to simply return no completion
-	 * proposals. If the user simply waits a moment and tries again, we will be
-	 * able to successfully calculate some proposals.
-	 * <p>
