Logs parser errors in Checkstyle manner. Parser can generate error messages. There is special error that parser can generate. It is missed close HTML tag. This case is special because parser prints error like "no viable alternative at input 'b \n *\n'" and it is not clear that error is about missed close HTML tag. Other error messages are not special and logged simply as "Parse Error...".
