Overview ruler not working anymore

Using latest eclipse stable release made public I found that overview ruler does not work or is not visible by default and no option to bring it back or show it.

It appears that the overview ruler options can be set in the annotations preferences but the overview ruler never appears in the editor.

The key feature of the overview ruler is that the
length of the ruler you see represents the complete file being edited, This provides a convenient way to jump to annotated parts of the file without excessive scrolling How these various annotations appear is defined by your Workbench > Editors > Annotations preferences

So it appears overview ruler on right never appears or does not work.
