CI runs fail using OracleJDK8 with
/home/travis/build/igniterealtime/Smack/smack-omemo/src/main/java/org/jivesoftware/smackx/omemo/element/OmemoBundleElement_VAxolotl.java:30:
warning - Tag @see: missing final '>':

OMEMO Encryption (Example 3)</a>."
Other JDKs do not report such an error.
Returning a generic would allow for
List<ExtensionElement> list = stanza.getExtension("foo", "bar");
to compile (Note the we are calling getExtension(), not
getExtension*s*()).
Users are encouraged to use the type safe getExtension(Class<? extends
ExtensionElement) variant instead.
Fixes SMACK-825.
By not directly depending on Bouncycastle (BC), we avoid conflicts between
different bouncycastle versions. It is also part of the developers job
to take care that all required security primitives are available. If
they are provide by BC or some other security provider should not be
up to Smack to decide.
We now only add BC as test dependency to satisfy this requirement when
the unit tests are executed.
- Reduce the amount of types that are subtypes of NamedElement. See
javadoc of NamedElement for rationale.
- Work more with XmlEnvironment in XmlStringBuilder.
- Some minor changes to XmlStringBuilder API.
by using PubSubManager.tryToPublishAndPossibleAutoCreate().
This also swaps the parameters of the method.
Thanks to Guus der Kinderen for suggesting this.
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.
Introducing Smack's own XmlPullParser interface which tries to stay as
compatible as possible to XPP3. The interface is used to either wrap
StAX's XMLStreamReader if Smack is used on Java SE, and XPP3's
XmlPullParser if Smack is used on on Android.
Fixes SMACK-591.
Also introduce JUnit 5 and non-strict javadoc projects.
This makes the system select the "best" available provider.
Also the 'BC' provider in newer Android version does not longer
implement certain Ciphers, which causes an NoSuchAlgorithmException if
the Cipher is requested explicitly by the 'BC' provider:
E/XmppService: XmppServiceConnection - Error while sending pending messages
org.jivesoftware.smackx.omemo.exceptions.CryptoFailedException: java.security.NoSuchAlgorithmException: The BC provider no longer provides an implementation for Cipher.AES/GCM/NoPadding.

Changes:
Rework integration tests
New structure of base integration test classes
bump dependency on signal-protocol-java from 2.4.0 to 2.6.2
Introduced CachingOmemoStore implementations
Use CachingOmemoStore classes in integration tests
Removed OmemoSession classes (replaced with more logical OmemoRatchet classes)
Consequently also removed load/storeOmemoSession methods from OmemoStore
Removed some clutter from KeyUtil classes
Moved trust decision related code from OmemoStore to TrustCallback
Require authenticated connection for many functions
Add async initialization function in OmemoStore
Refactor omemo test package (/java/org/jivesoftware/smack/omemo -> /java/org/jivesoftware/smackx)
Remove OmemoStore method isFreshInstallation() as well as defaultDeviceId related stuff
FileBasedOmemoStore: Add cleaner methods to store/load base data types (Using tryWithResource, only for future releases, once Android API gets bumped)
Attempt to make OmemoManager thread safe
new logic for getInstanceFor() deviceId determination
OmemoManagers encrypt methods now don't throw exceptions when encryption for some devices fails. Instead message gets encrypted when possible and more information about failures gets returned alongside the message itself
Added OmemoMessage class for that purpose
Reworked entire OmemoService class
Use safer logic for creating trust-ignoring messages (like ratchet-update messages)
Restructure elements/provider in order to prepare for OMEMO namespace bumps
Remove OmemoManager.regenerate() methods in favor of getInstanceFor(connection, randomDeviceId)
Removed some unnecessary configuration options
Prepare for support of more AES message key types
Simplify session creation
Where possible, avoid side effects in methods
Add UntrustedOmemoIdentityException
Add TrustState enum
More improved tests
