This is a complete redesign of what was previously
XmppNioTcpConnection. The new architecture allows to extend an XMPP
client to server (c2s) connection with new transport bindings and
other extensions.
Those exception are caused by I/O operations in the OmemoStore, which
is now declaring that it throws those (since it is not uncommon for
I/O operations to cause IOExceptions). After all, this is nicely
demonstrated as this change is caused by switching with this commit to
the Android API 19 compatible methods in FileBasedOmemoStore, which
throw.
The library can not decide what to do in case of those exceptions,
hence it is sensible to expose them to the user.
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.
