The Java view now reads what FILIUS 2.14 keeps for its e-mail programs: the server's domain, switch and bean accounts with their mailboxes, and the accounts of /mailserver/konten.txt, which Java reads at every simulation start and which so win over the bean list; the client's three folders and address book, and its account from /konten.txt (no bean holds it). javaEmail.ts ports the bean setters and both file readers (stringZuListeBenutzerkonten, EmailKonto(String)); javaString.ts Java's trim, split and StringTokenizer; javaFileSystem.ts the file lookup, now shared with the DNS server, with the four non-ASCII units Java's equalsIgnoreCase also takes for an ASCII letter (measured over the BMP). Checked against Java on the corpus (the oracle dumps the e-mail state) and on 43 account files read by EmailServer.kontenLaden and EmailAnwendung.laden (EmailFileCases). Found: older files keep recipients as strings in the typed lists; a getter copy of the sender is filled and set back; one short server line makes Java throw for the whole file; a message with an empty text is lost on reading; a broken last client line empties the account.
