This meant a client could request a -PLUS mechanism that was never advertised, and the eligibility check would pass — the rejection only happened deep inside the Java SASL implementation rather than as a clean protocol-level failure. This commit moves the channel binding filter into getAvailableMechanismsForClientSession, making it the single source of truth for session-available mechanisms. getSASLMechanismsElement now simply iterates the result without additional filtering logic.

This commit wires the two together at all three integration points defined by the specifications. 1. Inline feature advertisement (XEP-0388 §6.3.1) SASLAuthentication.getSASLMechanismsElement() now adds an element (urn:xmpp:sm:3) inside the child of the SASL2 feature, but only when stream management is globally active. 2. SM inside Bind2 (XEP-0386) A new Bind2InlineHandler implementation, Bind2StreamManagementHandler, handles elements that arrive inside the Bind2 element. It calls the new StreamManager.enableAndBuildElement() method (which performs the same work as the existing private enable() but returns the element instead of sending it) and adds the result to the element in the SASL2 stanza, so the client receives everything in a single round-trip. The handler is registered in SessionManager.start() and unregistered in SessionManager.stop(). 3. SM inside SASL2 (XEP-0388 §6.3.2) When a client includes a element inside its SASL2 stanza, SASLAuthentication.handle() stores it on the session. After SASL authentication succeeds, authenticationSuccessful() detects the stored element and calls the new StreamManager.processSasl2Resume() method. That method mirrors the existing startResume() logic but calls the new LocalSession.reattachForSasl2() instead of reattach(): the new variant takes over the connection and builds the element without sending it, so the caller can embed it inside the SASL2 stanza. Supporting refactors - StreamManager.onResume() is decomposed into buildResumedElement(), processClientAcknowledgementPublic(), and redeliverUnackedStanzas() so the SASL2 resume path can reuse the same logic without duplicating it. - StreamManager.enable() is decomposed into enableInternal() (returns the element) and the original enable() (sends it), with the new public enableAndBuildElement() delegating to enableInternal(). - LocalSession gains reattachForSasl2() alongside the existing reattach(). Tests - StreamManagerTest: three new tests for StreamManager.featureElement(). - Bind2StreamManagementHandlerTest: seven tests covering enable/resume attribute parsing, failure handling, and rejection of unexpected elements. - SASLAuthenticationTest: three new tests verifying that the inline feature is present in SASL2 advertisements when SM is active, absent when SM is inactive, and absent from SASL1 advertisements entirely.

Previously, reattachForSasl2() called redeliverUnackedStanzas() directly, which meant stanzas were sent before was even delivered to the client, let alone the post-success stream features. Fix: - Add a boolean flag pendingSasl2Redelivery to StreamManager, with setPendingSasl2Redelivery(boolean) and redeliverIfPendingSasl2(JID). - reattachForSasl2() in LocalSession now sets the flag instead of calling redeliverUnackedStanzas() directly. - StanzaHandler calls redeliverIfPendingSasl2() immediately after delivering stream features following a successful SASL2 authenticate or response, ensuring the correct ordering: 1. (with embedded ) 2. stream features 3. unacknowledged stanzas redelivered Three new unit tests in StreamManagerTest verify the flag semantics.
