If the successor's module is disabled then the vertex may be null. In
this case, we can simple continue with the next successor in the list.
Previously, due to d33a5a23c3 ("[core] Introduce
Builder.failOnUnknownStates() and unit tests") this would trigger an
assert in addOutgoingEdge().
Fixes: d33a5a23c3 ("[core] Introduce Builder.failOnUnknownStates() and unit tests")
The previous approach of emitting a severe log message when a
state (descriptor) was unknown was misleading. There are valid cases
where some states are not known, if, for example, a module was
explicitly disabled.
Using Builder.failOnUnknownStates() in unit tests is far cleaner, as
the existence of unknown states is tested in a controlled environment:
one where are states are supposed to be known.
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.
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.
