See bug 53359: Request for <Aliases> or <Alias> as element inside <Context> <Context> aliases attribute should allow whitespace to surround both the "," and "=" delimiters. For example: <Context aliases="/EDSILabCatalog= c:/xampp/htdocs/cLabs/EDSILabCatalog, /EDSILabs = c:/xampp/htdocs/cLabs/EDSILabs, /Global = c:/xampp/htdocs/cLabs/Global, /Skyline = c:/xampp/htdocs/cLabs/Skyline, /Sun = c:/xampp/htdocs/cLabs/Sun, /Sunset = c:/xampp/htdocs/cLabs/Sunset, /Tech2000 = c:/xampp/htdocs/cLabs/Tech2000" />
Fixed in trunk and 7.0.x and will be included in 7.0.28 onwards.
