javaBeansWriter.ts writes what java.beans.XMLDecoder reads — the
counterpart of javabeans.ts and the base of the .fls writer. Its input says
explicitly what Java should do: construct a class with typed arguments, call
setters, getters (with statements on their result), methods and indexed
access; an object reached twice is written once with an id and referenced
after. Unlike XMLEncoder it writes what it is given, defaults included.
What XML 1.0 cannot hold (controls, lone surrogates, U+FFFE/F) and a CR,
which XML would read as a line break, are written as <char code>.
Checked by Java itself: nine files of the writer (strings with every kind
of odd unit, all primitive types including NaN, -0.0 and a long beyond
2^53, collections, maps, shared objects, Rectangle, Color, FILIUS beans with
getter chains, arrays, indexed access, a static constant) are read by
XMLDecoder in the Java oracle (BeansDump), which describes what it got and
collects the errors the decoder would only log. Mutation probes regenerate
the files and let Java read each mutant.

Java stays the reference for the .fls format, but its errors are no longer
copied. The Java oracle still measures Java as it is; each deliberate
departure is named in the tests with its reason (JAVA_BUGS) and must really
depart. The corpus - what Java itself writes - still reads exactly as in
Java.
- /dns/hosts: a label may start with a digit, holds no backslash, and the
last one is not all digits (RFC 1123, RFC 3696); A, MX and NS are read in
any case (RFC 4343); a negative TTL is invalid, so 3600 (RFC 2181). Also
for the e-mail server's domain.
- /mailserver/konten.txt: empty fields count (Java's StringTokenizer skips
them and shifts the rest, so an empty password breaks the account); a
short line alone is left out, with a warning (Java throws for the whole
file); a message keeps an empty text or subject (Java's split loses it);
a ";" in an unescaped subject stays in the message; CRLF lines.
- /konten.txt: the last complete line is the account, also with an empty
address (Java takes the last line and loses the account); CRLF lines.
- Static DHCP assignments: a broken entry alone is left out (Java loses
every entry after it).

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.

Java's DNS server reads its records from the text file /dns/hosts on every
query. dnsHosts.ts ports that reading (DNSServer.leseRecordListe,
ResourceRecord, Dateisystem.holeDatei) and keeps in the model the records
Java answers: type exactly A, MX or NS, and a name Java accepted. The file
stays in the file system as it is.
Both oracles read 76 hand-picked hosts files (dns-hosts.cases.txt): the
Java oracle through DNSServer.holeResourceRecords (DnsHostsCases), the
Swift oracle through TopologyDNSHostsFileCodec (--dns-hosts). The Java view
matches Java on every case; the model matches Swift except for 33 named
cases in twelve reasons: Java splits at single spaces and LF only, has no
comments or "IN", turns a TTL that is no int into 3600, keeps duplicates,
and empties names with a leading digit. The Swift dump now carries each
server's records; the corpus comparison covers them on 16 files.

PeerToPeerAnwendung's constructor rolls its peer limit (3, 4 or 5). The
getter defaults measured it once each run — 4, then 5 — and c48d15d
committed 5 as a default. GetterDefaults now constructs every class 64
times and writes a value that varies as {"random": [...]}; the decoder
answers a reference to it as unresolved, and the topology layer reports
a peer limit the file does not set as null.

readSystemSoftware lists a PC's or notebook's installed applications with
the settings the model needs: server applications switched on and their
port, the generic client's target, DNS recursion, web server virtual
hosts, Gnutella's peer limit and the personal firewall (on by default,
unlike a router's). Defaults the file leaves out are measured in Java.
All 23 corpus files match Java.
Two examples install an application of their own (Accumulator,
Broadcast), compiled into projekt/anwendungen; it is left out with a
warning, as this reader cannot run Java classes. It must survive a save.

readSystemSoftware reads a host's file system: Java's tree of
DefaultMutableTreeNodes, directories named by their user object, files
as Datei (by setters or the three-argument constructor), rooted at
arbeitsVerzeichnis (up to 1.10) or root. All 23 corpus files match Java,
every file compared by name, type and the SHA-256 of its content.
Routers and home routers have files in Java too, but their constructor
makes them from templates (the start page of the firewall's web
interface); they are not in the file and not claimed here.

readSystemSoftware adds the DHCP client switch and server settings of
every IP stack, a home router's static NAT table (port forwarding) and a
modem's mode, port and address. All 23 corpus files match Java.
Static DHCP assignments follow setStaticAssignedAddresses: each entry is
split at Java whitespace (the same 25 characters as Character.isWhitespace,
measured over the BMP), and an entry without MAC and IP ends the list, as
Java throws there.

readSystemSoftware adds to each node what the topology needs from its
system software: a switch's SSID and learning time, a host's wireless
SSID, a router's RIP switch, the manual routes and the firewall of a
router or home router. All 23 corpus files match Java.
- A router's firewall is one object its constructor hangs in two places;
the corpus writes it under the web server's "konfig" plug-in. The
places are merged.
- The decoder keeps entries a constructor made in a map, reached by
get(key) (installed applications), like the elements of a list.
- The Java oracle loads every file twice and writes values that differ
as null: what FILIUS rolls (MACs, a switch's SSID) without text search.

readTopology maps the decoded JavaBeans graph to devices, cables and
documentation items the way SzenarioVerwaltung.netzwerkLaden does: the
kind from the Java class (the palette label is not file data), devices
without bounds at 0,0, interface values through Java's setters. All 23
corpus files match Java field by field.
Found on the way:
- listItems mixed a constructor's elements with added ones; a router's
second interface was lost. Lists now replay add/set in order after the
elements the constructor made.
- The first 0 of a file may be SwingConstants.CENTER; measured like the
getter defaults.
- IP.ipCheck (javaIp.ts) measured on 46 cases: empty tokens skipped,
signs, leading zeros and BMP digits of any script accepted.
- The Java oracle took lower-case MACs in a file for random ones (8
interfaces); it now compares case-insensitively and reports the host
name flags.

XMLEncoder shares equal Integer objects, so a node's x coordinate can be
written as a reference to the result of JSidebarButton.getIconTextGap().
GetterDefaults constructs the classes like XMLDecoder does and records
what the getters return (packages/fls/src/javaDefaults.json).

tools/java-oracle builds FILIUS at 6640354 and loads every .fls through
its own private loader under Xvfb. All 23 files load with every node
positioned and every cable resolved (Swift: 20 of 25 nodes in the
Internet example). MAC addresses FILIUS generates are left out, so two
runs are byte-identical.
