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).
This means that users get now exceptions with helpful error messages
instead of the dreaded ClassCastException, like
java.lang.ClassCastException: org.jivesoftware.smack.packet.StandardExtensionElement cannot be cast to org.jivesoftware.smackx.mam.element.MamElements$MamResultExtension
at
when StanzaView.getExtension(Class) is used to retrieve the extension.
When sending a stream-open-like element, it depends on the actual used
transport which element is send. For example, RFC6120-style TCP uses
<stream>, whereas the Websocket binding for XMPP uses <open/>.
Most of the times when we construct a stream-open-like element, we
want the jabber:client namespace. Hence add a constructor that does
select the namespace implicitly.
Before the existence of AbstractStreamOpen, StreamOpen sufficed our need
during sending an open stream element. Since the intention behind
introducing AbstractStreamOpen is to allow underlying transports provide
transport specific opening streams, these changes will further support
the cause.
This commit will allow us to send transport specific open element
which should be inherited from AbstractStreamOpen.
This PR aims to provide parseXrdLinkReferencesFor() method the ability
to parse forward to the first START_ELEMENT tag.The HttpLookupMethodTest
tests the HttpLookupMethod class by parsing String. This makes use of
PacketParserUtils.getParserFor(String), which already does forward
winding to reach START_ELEMENT. However when fetching endpoints from a
remote host meta data, PacketParserUtils.getParserFor(InputStream) is
used which doesn't do winding in any form. And thus, even though
HttpLookupMethodTest tests pass, this implementation would crash while
parsing remote host-meta.
We previously only set 'connected' after connectInternal()
returned. This could lead to notifyConnectionError() ignoring stream
error exceptions, e.g. when establishing TLS which happens also in
connectInternal(), because 'connected' was still 'false'.

We now set 'connected' to 'true' as soon as the transport (e.g. TCP,
BOSH, …) is connected. While this is in other ways also sensible, it
also allows notifyConnectionError() to handle exceptions in the early
connection stage.
Thanks to Eng Chong Meng for reporting this.
To make it clear that this will either return if the condition is
true *or* if a connection exception happened.
Also introduce waitFor(), which is deliberately not named
waitForCondition() because it carries a different semantic.
Synchronize notifyConnectionError() so that only one exception is
handled and remove the ASYNC_BUT_ORDERED usage here. The
ASYNC_BUT_ORDERED was added with 7d2c3ac9f ("Do not call synchronized
methods in reader/writer thread"), but is no longer necessary, since
the Semaphores where replaced with conditions in the previous commit.
This continues the design started with e98d42790 ("SmackReactor/NIO,
Java8/Android19, Pretty print XML, FSM connections"), where the
exceptions that caused an operation to fail, are not recorded within
SynchronizationPoint but within the connection instance itself.
Since d65f2c932 ("Bump Error Prone version to 2.3.4 and fix new bug
patterns") the channel selected callback is no longer a final field of
the connection instance, hence it may be come null even if the
connection instance is still strongly referenced. Also the
ConnectionAttemptState class uses simply a lambda as callback, which
is also not strongly referenced otherwise.
The "channel selected" callback was wrapped in weak reference, so that
connection instances could get gc'ed if they are still connected but
the user lost all references to them. In this case, the weak reference
to the connection instance would become 'null' and
selectionKey.cancel() would be called.
This change means that a socket and its selection key of a "leaked"
connected connection instance continues to be part of the reactor. But
this may not be that bad: first, users are expected to manager their
connection instances, and disconnect them before they are
discarded. And secondly, at some point the connection likely will get
disconnected, and in this case, the socket and its selection key will
be removed from the reactor.
This moves the logic in AbstractXMPPConnection.getSmackTlsContext()
into the ConnectionConfiguration constructor.
Also introduce SslContextFactory and use it in
ConnectionConfiguration.
The field XMPPInputOutputStream.flushMethod was not initialized, which
could cause an NPE in the "switch (flushMethod)" found in
Java7ZlibInputOutputStream.getOutputStream().
