The problem is that the FilenameUtils's normalize(String) method returns "null" if it thinks the file names are invalid - which in your case it seems to be doing so for both file names. So I guess theres two issues here - you're right the error is misleading and FilenameUtils should check the names again after calling normalize() for nulls and throw a more appropriate message. > Should I fill a JIRA issue for that?
