Babbler Version 0.7.0 Released

Version 0.7.0 of the XMPP Java library has just been released!

As always you can find the artifacts in Maven Central:


Release highlights are support for WebSocket connection, the new XMPP Address Format (RFC 7395), asynchronous API for IQ queries and XEP-0198: Stream Management (which is still a bit experimental).

Some API has also been revised for less ambigious and easier usage, e.g. timeouts are now represented by java.time.Duration instead of a int/long (which somtimes were seconds, sometimes milliseconds) and the xml:lang attribute is now represented by java.util.Locale instead of String to prevent improper usage.

Here's a more complete list of changes:
  • Add support for XEP-0198: Stream Management
  • Add support for WebSocket connection method (RFC 7395).
  • Update Jid class to the new XMPP Address Format (RFC 7622)
  • IQ queries can now be executed asynchronously (non-blocking) using Java 8’s java.util.concurrent.CompletableFuture API.
  • Represent xml:lang attributes as java.util.Locale, not as String.
  • Represent timeouts as java.time.Duration instead of int/long for better clearness.
  • Add a very minimalistic DNS resolver for resolving SRV and TXT records in order to remove the dependency to com.sun.* classes.
  • Add more ReconnectionStrategy implementations.
  • Check connected state of socket before connecting (to prevent SocketException when a SocketFactory provides a connected socket)
  • Add XmppSession#isAuthenticated() method.
  • Add static XmppSession#addCreationListener() method to allow to listen for newly created sessions.
  • Update XEP-0080 to version 1.9 (add altaccuracy element).
  • Add API to destroy a MUC room without a reason.
  • More documentation, e.g. clarify the use of ConnectionConfiguration#secure()
  • Don’t include an empty body in Message Delivery Receipts.
  • Add correct XML names to component namespace stanzas.
  • Eagerly release unused port to prevent ports-leaks due to delayed GC
  • Improve thread-safety during connect() and login()
  • Fix encoding issues, caused by missing UTF-8 encoding, mainly in the debugger.
  • XEP-0033: Address should have extensions.
  • Add workaround for a JDK bug causing memory issues and high CPU.
  • Add documentation for custom SASL authentication.
