Bug 45187 Double clicking in Package Explorer highlights class name [package explorer]
Rurn on "Show members in Package Explorer" Using EclipsePlugin as an example class name, when double clicking on a method in that class, like getDefault, getDefault is selected in the editor, but the highlight in the package explorer jumps to EclipsePlugin instead of remaining on getDefault. This is the behavior if "Link with editor" is turned on. If it is turned off, the highlight doesn't jump.

			setTitleToolTip(getToolTipText(input));
