The connection close listener initiates a presence broadcast to
advertise its "unavailable" status. The current connection must be
marked closed before this occurs, so the presence stanza will not be
delivered to the newly closed connection.

Note that the synchronized block alone does not accomplish this because
the presence broadcast is delivered via that same thread that is
currently closing the connection, thus it already possesses the sync
object lock.

Also, note that the SessionManager should exclude the originating JID
when sending presence broadcasts to the user's other available
session(s).

This patch is to prevent a stack overflow in certain exception cases
where a connection has been closed, but its corresponding session is
still present in the routing table.

OF-855/OF-857 improvements

Also decrease the size of the critical section the lock protects.

and remove null checks.

Related to OF-855.

This patch fixes several NullPointerExceptions that were observed in an
cluster when running under high load and latency, including related
issues in the BOSH connector and hazelcast plugin. Some related logging
improvements are also included.

Some of the NPEs were generated during the startup phase before the
server was fully initialized. These have been corrected by checking
appropriate "ready state" indicators.

In general, sessions hosted in remote cluster nodes that cannot be
addressed due to timeouts during remote task execution should be
considered temporarily "unavailable" to the cluster member that
initiated the call.

Check the underlying connection for a given session before delivering a
packet; if the connection is missing, clean up session and resend packet

Use a lock to ensure the integrity of IoSession (MINA), especially when
using compression or TLS filters

OF-629: Here Lies XMPP Session

Update the advertised stream features to mark the xmpp-session
capability as optional (per
http://tools.ietf.org/html/draft-cridland-xmpp-session-01). Current
implementation is already no-op.

OF-861 Disable SSLv3 for HTTPBind and Admin Console

Disable SSLv3 for socket connections to avoid POODLE vulnerability.

Upgrade Hazelcast plugin to HZ 3.3.3

OF-860: Self-presence is not broadcast if room has more than one occupant

The problem here was, that the presence's 'to' attribute was overridden on each iteration, making the if statement fail after the first iteration.

ofmeet plugin - ready for openfire 3.10 beta release

OF-859: Fix SQL syntax error [pubsub]

Update statement for default node configuration was missing a comma

OF-857: Properly configure Jetty connectors

Update for earlier fix to properly construct and initialize HTTP/S
connectors using configurable resource limits.

OF-857: Improve thread pool management

Update default QTP configuration for admin console and BOSH connectors;
added new configuration property "adminConsole.serverThreads" with a
default of 2

OF-859: Pubsub fix; misc cleanup

This fixes a problem with a static final reference in the Node.class. It
also addresses a couple of minor issues discovered during pubsub
testing:
- PubSubPersistenceManager should return an editable collection rather
than a read-only collection for published items
- SequenceManager defaults should use a blocksize of 5 for frequently
used tables
- LocaleUtils should catch and log a MissingResourceException and return
the key in lieu of the missing value (by convention)

OF-857: Fix C2S locking issues

Updates the MINA 2.0.9 core to fix a locking issue documented here:
https://issues.apache.org/jira/browse/DIRMINA-995

Also updates connection manager and thread pool configurations to better
allocate resources within the JVM.
