Description Andrew Gvozdev CLA 2012-01-25 11:16:36 EST 
It is possible to represent workspace root with a slash and "Is workspace path" in Paths&Symbols Includes. However, that causes NPE when Project Explorer tries to determine icon to be shown. It seems as much confused what icon to show as developers in bug 330750.
