Introducing Smack's own XmlPullParser interface which tries to stay as
compatible as possible to XPP3. The interface is used to either wrap
StAX's XMLStreamReader if Smack is used on Java SE, and XPP3's
XmlPullParser if Smack is used on on Android.
Fixes SMACK-591.
Also introduce JUnit 5 and non-strict javadoc projects.
and also call notifyConnectionError() on exception thrown by
openStream().
In hindsight I wonder why openStream() was ever called in the writer
thread, as it only caused unnecessary synchronization overhead, as can
be seen by the initialOpenStreamSend synchronization point.
Smack will throw an IllegalArguementException if extremely
long reply timeouts are tried to be set. I assumed currentTimeMilli()
to be the boundary condition as per SMACK-718
XEP-0060 prohibits publishing a request that contains an item to a node that
is both 'notification-only' and 'transient' (section 7.1.3.6)
In commit 8ed872ca63 the existing pubsub publication
test was modified (to resolve a different issue) to operate on a node that's both
'notification-only' and 'transient'. This resulted in a test that should return
an error, even though the test implementation didn't expect one.
This commit explicitly verifies that publishing an item to such a node causes
an error to be returned. A new test is added that verifies that publishing an
event notification does succeed.
The Smack Integration tests can use an admin account to provision
accounts that are used by the tests. This admin account uses an XMPP
connection to interact with the server-under-test.
When the tests are over, this account should be disconnected
explicitly, to prevent stream management from keeping it alive longer
than it needs to.
This makes the system select the "best" available provider.
Also the 'BC' provider in newer Android version does not longer
implement certain Ciphers, which causes an NoSuchAlgorithmException if
the Cipher is requested explicitly by the 'BC' provider:
E/XmppService: XmppServiceConnection - Error while sending pending messages

Thanks to Marcel Heckel for reporting this.
Fixes SMACK-861.
In case an exception happens in connect()/login() the
'disconnectedButResumable' boolean may (still) be set. Which causes
only one of the reader and writer threads to exit, typically the
reader thread, because shutdown() will bail out very early. This
leaves a dangling (writer) thread causing memory leaks and deadlocks
on a subsequent connect()/login().
