I ran into a problem where an XML file had invalid hidden characters that prevented the file from being parsed.
Currently, Windup reports invalid XML in the application source file report. This means you have to drill down to the file level to determine if the file was evaluated or if it reported "Unparseable XML File - This file could not be parsed". If you have hundreds or thousands of files, it would be difficult to determine which XML files were not processed due to invalid XML.
It would be much more valuable to put all this information in one report so you could see at a glance which files were not evaluated for migration.
