A new oracle, InstallRun, installs each of Java's programs on new
computers, all of them on one, each installed and removed again, and a
DNS and an e-mail server installed again after their removal; Java saves
the result as a project. A new program is switched off (a computer's
firewall is on), makes the folders and files it lacks (the web server's
start page in FILIUS' language and its picture, /peer2peer,
/mailserver/konten.txt, /dns/hosts), and removing it takes its settings
and leaves its files; a server installed again reads its records or
accounts from them. Java installs in the order of its list and starts
the program at once.
The document's setSoftware does the same, checked against Java's saved
installation. The core knows what a program makes in the files and
installs or removes a program while the simulation runs; the room
watches the document's programs and hands changes to the engine, so a
new command line works at once. The desktop offers Java's dialog with
two lists, arrows, double click and apply changes.
Also: Java's file may name a number it rolled by the result of any
getter (an idref, here a thread's priority); GetterDefaults now
measures the priority of the saved thread classes, which the import
read as 0 before.

ExampleRun opens an example as FILIUS opens it (SzenarioVerwaltung.laden
into the window's lists), starts it as the action mode does, plays a
story and writes every card's frames and tables, the calls, the
addresses and the RIP tables' changes. examplesJava.test.ts reads the
same file with this package's reader and runs it in the core
(projectSnapshot, new): routing (internetwork_komplett), DHCP
(einfaches_rechnernetz_komplett), DNS (dns_server), NAT
(nat_with_mapped_port) and firewall (Internet_Komplett_..._DE) match
card by card.
Found and fixed: a host's ipForwardingEnabled, which Java saves and
obeys, was unknown to the reader, the model, the core, the writer, the
export and FlsOracle; and Java's ARP learns only from a request for its
own address or a reply. Named Java bugs: a ping without a gateway throws
a NullPointerException; a home router drops the answer of a second
remote end. Open: Java picks between equally long RIP routes by thread
timing.

Where the Swift template departs from Java's filius.software.rip, Java's
code rules: a learned route gets 16 hops at the router's next beacon after
it expired (RIPTable.check), not when it expires; messages count from any
source port; each router draws its pauses from a random of its own (Java:
an unseeded Random per router), which the core seeds from the scenario and
the router's id (ripSeed), so that the Java oracle can give it the same.
A route of hop count 0 to each own network, the first beacon after a
second, then every 25.2 to 35.2 s; a message per interface without the
routes through it; a new route or a longer one from the same router sends
at once; forwarding by the table alone, fewest hops before longest mask.
Messages are read with Java's parser (javaIpCheck, javaParseInt, moved from
fls to core for it).

exportProject.ts is the counterpart of importProject.ts: from the editor
model to the Java view topologyWriter.ts writes. Step X1, the topology:
each node becomes the Java device of its kind with name, position and label
flags; its ports become interfaces or ports; each link a cable drawn
between its nodes; each documentation item a GUIDocuItem. A port's MAC is
the one the simulation uses (the file's, or one derived from the port id);
a router's gateway and DNS server go to every interface, as Java's own
setters do (Java reads the first interface's only). A host with a wireless
card joins a switch by a wireless cable, the only wireless connection Java
makes. The import now enables a host's wireless by Java's card flag, also
without an SSID, where Swift enables it for every SSID.
Checked by Java: every corpus file, imported, exported and written, loads
in Java FILIUS to the topology of the original up to named departures of
the model (a derived MAC where Java rolls one at each load; documentation in
render order, with the model's empty text, Dialog 12 and minimum size where
Java has none or less). A synthetic model adds a label with IP and MAC,
positions between pixels, a five-port switch, a wireless notebook, a
three-interface router and a half-transparent bold text. 17 mutation
probes, each loaded by Java, were all caught.

topologyWriter.ts writes konfiguration.xml from Java's view of a project:
the version line, the node items (label position, device with name,
host label flags, interfaces or ports), the cable items and the
documentation items. What a device's constructor makes is changed through
getters, as XMLEncoder does, and more is added; fewer than it makes set the
list anew. Cable ends name the port objects the getters return (the writer
now names a getter's result, <void id="Port0" property="port"/>), and each
cable carries the nodes the editor draws it between.
Checked by Java against Java: every corpus file, read and written again,
loads in Java FILIUS (the oracle's loading method, --sha256 ties its result
to the written bytes) to the same devices, names, positions, interfaces,
cables and documentation as the original; so does a synthetic topology with
what the corpus never sets. The oracle and the reader now also report a
cable's drawing ends (JCablePanel ziel1/ziel2): in the corpus the nodes it
joins, for all 183 cables. Mutation probes rewrite the files and let Java
load each mutant.

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.

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.

importProject builds what the simulation core runs from Java's view of a
file: nodes with kinds and ports, links between port ids, device and
interface IP configurations, documentation items with Swift's derived
ids. The core gains the model types it needs (node, link, graph,
documentation item), ported from filius-ipad.
Checked against the Swift import, which the Swift oracle now writes in
full (corpus.swift.json, "state"), on the 13 files Swift reads
completely. Two differences are intended and named in the test:
- a device the file leaves unnamed has Java's default name
("Switch / WLAN"), not Swift's;
- multicast_server.fls: useIPAsName refers to a shared Boolean that
Swift cannot follow; Java shows the IP address, and so do we.
All 23 files import with as many devices and cables as Java has, and an
imported example pings across its router in the core.
Port counts of switches and routers follow Java's lists instead of
Swift's guess from references.

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.

A generic interpreter for the .fls configuration: objects, properties,
calls, indexes, static fields and factories, Field.set, and id/idref
anywhere — including getter results, answered from the measured Java
defaults or reported as unresolved. All 23 corpus files: class and
position of every node as Java reads them, also where Swift loses nodes.

Reader and writer ported from filius-ipad with the same path policy,
limits and error codes; DEFLATE via fflate, cut at the declared size
like Apple Compression. 54 tests: the Swift archive rejection tests,
DEFLATE edge cases, and all 23 corpus files cross-checked against
fflate.unzipSync and round-tripped.
