This is a master bug to track the status of combining two arrays into one. These code are mostly in Exception related files.
A simple grep shows there are several instances: Source/WebCore/Modules/indexeddb/IDBDatabaseException.cpp Source/WebCore/Modules/webdatabase/SQLException.cpp Source/WebCore/dom/EventException.cpp Source/WebCore/dom/RangeException.cpp Source/WebCore/fileapi/FileException.cpp Source/WebCore/fileapi/OperationNotAllowedException.cpp Source/WebCore/svg/SVGException.cpp Source/WebCore/xml/XMLHttpRequestException.cpp Source/WebCore/xml/XPathException.cpp I'll track each change in one bug.
As all the bugs this bug depends on are solved, mark this master bug as resolved as well.
