Bug 183217 suppress duplicates leaving whitespace
I am not certain this is a bug, but if I set suppress duplicates on all the columns, I still get whitespace for suppressed rows. 2.1.2 did not do this. This issue happens in the M6 build.

{
				AbstractArea child = (AbstractArea) iter.next( );
				totalHeight += child.getAllocatedHeight( );
			}
			int offset = cell.getContentHeight( ) - totalHeight;
			if ( offset > 0 )
			{
				if ( IStyle.BOTTOM_VALUE.equals( verticalAlign ) )
				{
					iter = cell.getChildren( );
					while ( iter.hasNext( ) )
					{
						AbstractArea child = (AbstractArea) iter.next( );
						child.setAllocatedPosition( child.getAllocatedX( ),
								child.getAllocatedY( ) + offset );
					}
				}
				else if ( IStyle.MIDDLE_VALUE.equals( verticalAlign ) )
				{
					iter = cell.getChildren( );
					while ( iter.hasNext( ) )
					{
						AbstractArea child = (AbstractArea) iter.next( );
						child.setAllocatedPosition( child.getAllocatedX( ),
