Bump Gradle from 6.8.3 to 8.10.2 and increase the minimum required
Java version from 8 to 11 (SMACK-953).
The switch from Java 8 to 11 caused some Bytecode portability issues
regarding NIO Buffers. Java changed with version 9 the return type of
some subclasses of Buffer to return the specific Buffer type instead
of the Buffer superclass [JDK-4774077]. For example, ByteBuffer.filp()
previously returned Buffer, while it does return ByteBuffer now.
This sensible change was not reflected by the Android API [1], which
means that AnimalSniffer rightfully started to complain that there is
no method "ByteBuffer ByteBuffer.flip()" in Android, there is only
"Buffer ByteBuffer.flip()", and those are incompatible methods on
Java's Bytecode layer.
As workaround, this changes
return charBuffer.flip().toString();
to
((java.nio.Buffer) charBuffer).flip();
return charBuffer.toString();
to restore the Bytecode portability between Android and Java.
Errorprone also got new checks, of which JavaUtilDate and JdkObsolete
are wroth mentioning.
JavaUtilData basically strongly recommends to use Java's newer time
API over java.util.Date. But since Smack was Java 8 until now,
j.u.Date is widely used.
Similar JdkObsolete mentions obsolete JDK APIs, like data structures
like Vector and Stack. But mostly LinkedList, which should usually be
replaced by ArrayList. And this is what this commit largely does.

After a room is destroyed, the MultiUserChat-stored representation of the 'join' state of any occupant should be updated to reflect that the user is no longer in the room.
This fixes a problem where an occupant (that not itself triggered the destruction) appears to continue be part of a room after its destruction.
Additional integration test assertions are added to check for the invalid state fixed by this commit.
fixes SMACK-949
Only list-multi and list-single fields require at least one value when
submitting a form. In other cases, for example XEP-0045's
muc#roomconfig_roomadmins, which is of type jid-multi, is used without
any values to reset the room's admins list.
Fixes SMACK-946.
The getRegistrationInfo() returns a registration form that may also contain a CAPTCHA.
We need to get the full Registration object to get the fields.
Also it should be possible to call it multiple times to update the form.

When an occupant gets its membership revoked in an members-only room, the appropriate method of registered ParticipantStatusListeners should be invoked.
MUC mediated invitations usually have the form
<message
from='coven@chat.shakespeare.lit'
id='nzd143v8'
to='hecate@shakespeare.lit'>
<x xmlns='http://jabber.org/protocol/muc#user'>
<invite from='crone1@shakespeare.lit/desktop'>
<reason>
Hey Hecate, this is the place for all good witches!
</reason>
</invite>
<password>cauldronburn</password>
</x>
</message>
(source: XEP-0045 Example 57.)
However, previous versions of XEP-0045 specified an additional <x
xmlns='jabber❌conference'> element to be included (see
implementation note in XEP-0045). Therefore, a legacy implementation
may emit a mediated invitations in the form of
<message
from="smack-inttest-mediated-invite-from-8ta77-hw9igz@conference.example.org"
to="smack-inttest-two-8ta77@example.org">
<x xmlns="http://jabber.org/protocol/muc#user">
<invite from="smack-inttest-one-8ta77@example.org"/>
</x>
<x xmlns="jabber❌conference" jid="smack-inttest-mediated-invite-from-8ta77-hw9igz@conference.example.org"/>
</message>
Unfortunately, this matches
MultiUserChatManager.DIRECT_INVITATION_FILTER because
GroupChatInvitation matches <x xmlns="jabber❌conference"/>. However
the message is not a direct invitation but a mediated one. Besides
this invoking the wrong listeners (direct vs. medidated) the value for
'inviter' that's used to invoke that listener will be false.
To fix this, extend DIRECT_INVITATION_FILTER with
NotFilter.of(MUCUser.class) to avoid matching those legacy mediated
invitations.

When Smack requests a subject change of a MUC, an error returned by
the server (eg: 'forbidden') should be propagated (as suggested by the
pre-existing javadoc).

When the incoming unavailable presence is signalling a nickname
change (303), then do not invoke userHasLeft(), because the user
actually does not leave but instead just changes its nickname.
Note that this would also have had fixed SMACK-942, as it would
resolve the deadlock. However, using a dedicated lock for
changeNickname() still seems sensible, and if its just to avoid a bit
of lock contention.
What this also fixes is that a MultiUserChat does no longer invoke its
listener-based callbacks after a nickname change, as previously, after
a nickname change, the userHasLeft() would have been invoked, which
tears down the listeners. This issue was found with
MultiUserChatOccupantIntegrationTest.mucChangeNicknameInformationTest().
Using this method used to result in a deadlock, as shown by these two threads

The changeNickname() method was synchronized and is userHasLeft(),
this caused a deadlock since changeNickname() awaits the presence that
is send as result of the nickname change. But this presence is also
processed in a listener which invokes userHasLeft(). However, this
invocation blocks as userHasLeft() is waiting on the montior currently
hold by the thread invoking changeNickname().
To fix this, we change changeNickname() to not take the MultiUserChat
monitor, but instead use a dedicate lock.
Fixes SMACK-942.
Calling write() in FillableForm's constructor causes a NPE because
write() makes use of requiredFields which has not been set at this
time. Furthermore, write() makes use of missingRequiredFields, which
is also populated in that loop. Therefore, we have to delay the
invocation of write() until requiredFields got set.
Thanks to Dan Caseley for reporting this.

This is a follow-up on 198c51356d ("Add initial support for XEP-0103
and XEP-0104: URL Address Information"), which
1. adds the entries to the support XEPs table
2. registers the provider
3. renames the package from url_address_information to urldata (aka.
the shortname of XEP-0130).
The default local address is often just "the first address found in the list of addresses read from the OS" and this might mean an internal IP address that cannot reach external servers. So wherever possible use the same IP address being used to connect to the XMPP server because this local address has a better chance of being suitable.
This MR adds the above behaviour, and two UTs to test that we use the local XMPP connection IP when connected, and the previous behaviour when not.
Exposes a method for a MUC to invite a user to the room, and adds a listener to the MultiUserChat listener to inform users of direct invitations they have received.
Fixes SMACK-932.
While markdown is easier to write, Smack's markdown documentation was
never tightly coupled with the source. For example, the markdown
documentation never provided links to the actual Java classes and
methods. This poses the risk that the documentation and the code
diverge over time. Furthermore, javadoc is constantly improving (for
example @snippet annotations) and I expect that one will be able to
write javadoc in markdown.
Fixes SMACK-928.
