While running the Smack integration tests, a line like this is printed to std-out somewhere
Available tests: 21 (Disabled 12 classes and 6 tests
There's a missing character on the end of that line, which makes the author of this commit twitch.
This commit adds the missing character, resulting in a line like this:
Available tests: 21 (Disabled 12 classes and 6 tests)
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>:

Instead of breaking in case the SSLEngine signals NEED_WRAP, which
leads to an endless loop while holding the
channelSelectedCallbackLock, we have to return, so that the
asynchronously invoked callback can aquire it, and do its work.
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.
