Bug 15844 [Exception Handling] SelectionChange events and NPE
Build 20020508 Due to new global actions there are now more objects listening to selection changes send out by a JFace viewer. We now had the case that one of the listener generated a NPE. As a result all listeners registered after that one didn't receive the selection change event. StructuredViewers should be more fault tolorant to exceptions when informing listeners.

* <code>SWT.CHECK</code> style bit.
 * The table shows its contents in a single column, with no header.
 * The viewer has no input, no content provider, a default label provider, 
 * no sorter, and no filters.
 * <p>
 * No <code>TableColumn</code> is added. SWT does not require a 
 * <code>TableColumn</code> if showing only a single column with no header.
 * SWT correctly handles the initial sizing and subsequent resizes in this case.
