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.
and FileTestUtil in favor of commons-io. This is required because
Eclipse won't put src/test code into the classpath of src/main
code (even though gradle was configured with an according
dependency).
- 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.
