This commit adds
- SmackReactor / NIO
- a framework for finite state machine connections
- support for Java 8
- pretty printed XML debug output
It also
- reworks the integration test framework
- raises the minimum Android API level to 19
- introduces XmppNioTcpConnection
Furthermore fixes SMACK-801 (at least partly). Java 8 language
features are available, but not all runtime library methods. For that
we would need to raise the Android API level to 24 or higher.
Add
- performSaslAnonymousAuthentication()
- performSaslExternalAuthentication(SSLContext)
- addEnabledSaslMechanism(String)
- addEnabledSaslMechanisms(Collection<String>)
to ConnectionConfiguration.Builder.
Instead of providing a special API call for anonymous authentication,
Smack now has a configuration builder method to set anonymous/external
authentication. This also removes a lot of duplicate code within
Smack.
Also move SASLAnonymous into o.j.smack.sasl.core.
Fixes SMACK-629.
