If the successor's module is disabled then the vertex may be null. In
this case, we can simple continue with the next successor in the list.
Previously, due to d33a5a23c3 ("[core] Introduce
Builder.failOnUnknownStates() and unit tests") this would trigger an
assert in addOutgoingEdge().
Fixes: d33a5a23c3 ("[core] Introduce Builder.failOnUnknownStates() and unit tests")
The previous approach of emitting a severe log message when a
state (descriptor) was unknown was misleading. There are valid cases
where some states are not known, if, for example, a module was
explicitly disabled.
Using Builder.failOnUnknownStates() in unit tests is far cleaner, as
the existence of unknown states is tested in a controlled environment:
one where are states are supposed to be known.
ExtensionElement is now a marker interface that requires all
implementation non-abstract classes to carry a static final QNAME
field (of type QName). This is verified by a new unit test.
Also FullyQualifiedElement is renamed to simply XmlElement. XmlElement
is used over ExtensionElement when implementing classes do not
statically know the qualified name of the XML elements they
represent. In general, XmlElement should be used sparingly, and every
XML element should be modeled by its own Java class (implementing
ExtensionElement).
Properly reply to IQ requests with feature-not-implemented or
service-unavailable. In case there is no IQ request handler but the IQ
namespace is known, we reply with feature-not-implemented, otherwise
with service-unavailable.
Appearently simply calling ClassLoader.getSystemResourceAsStream()
works on Java SE but not on Android. But our FileUtils are able to
load the resource stream on Android.
This also lifts a bunch of logic from smack-websocket-okhttp into
smack-websocket. Furthermore, the following subprojects require now
Java 11:
- smack-integration-test
- smack-omemo-signal-integration-test
- smack-repl
- smack-websocket-java11

This also resulted in a refactoring of the Providers and parsing
Exceptions. NumberFormatException and ParseException can now be thrown
directly, the wrapping in a SmackParsingException is down at a higher
layer, i.e. in AbstractProvider.
Assume the element
<foo:bar xmlns='namespace' xmlns:foo='foo-namespace'/>
then the <bar/> element's namespace is 'foo-namespace', but the
default namespace is 'namespace'. And this is the namespace that
scopes into inner elements.

Do net put an ack to the queue if it has already been shutdown. Some
servers, like ejabberd, like to request an ack even after we have send
a stream close (and hance the queue was shutdown). If we would not
check here, then the ack would dangle around in the queue, and be send
on the next re-connection attempt even before the stream open.
See the following trace of the MUC bookmarks integration test. The
fact that it is a MUC test does not matter, but this test does
disconnect the connection and reconnect it. Not how the server,
ejabberd in this case, requests an SM ack by sending an <r/> even
though we already send the </stream:stream>:

Smack currently does unnecessary escaping of XML text, where it
escapes e.g. '"' to '"'. This bloats the stanza size, especially
if JSON payloads are involved.
Fixes SMACK-892 (although there are probably still places where
XmlStringBuilder.escape() is used when XmlStringBuild.text() could
have been used).
