Bug 121727 [Viewers] ContentViewer.getLabelProvider javadoc is wrong
Original javadoc: Returns the label provider used by this viewer. <p> The <code>ContentViewer</code> implementation of this method returns the label provider recorded in an internal state variable; if none has been set (with <code>setLabelProvider</code>) a <code>SimpleLabelProvider</code>... Corrected javadoc: Returns the label provider used by this viewer. <p> The <code>ContentViewer</code> implementation of this method returns the label provider recorded in an internal state variable; if none has been set (with <code>setLabelProvider</code>) a <code>LabelProvider</code>... Note the change from <code>SimpleLabelProvider</code> to <code>LabelProvider</code>.
