I used Worklight 5.0.6 to create a HTTP adapter to retrieve a UTF-8 XML. However, it returns failed and no data is retrieved. But when I change the file to UTF-8 without BOM, it can be retrieved successfully. (The XML already contains charset equal to UTF-8 in first line.) Is it a limitation for adapter only retrieve XML in UTF-8 without BOM but not solely UTF-8? or it is a bug?
