-------------------------------
Summary: Qpid JMS 2.3.0: setClientID() Hangs Indefinitely at
BalancedProviderFuture.sync()
Key: QPIDJMS-609
URL: https://issues.apache.org/jira/browse/QPIDJMS-609
Project: Qpid JMS
Issue Type: Bug
Components: qpid-jms-client
Environment: * {*}Qpid JMS Client Version{*}: {{2.3.0}}
* {*}Broker{*}: ActiveMQ {{6.1.4}} (AMQP 1.0)
* {*}Java Version{*}: Amazon Corretto JDK 21
Reporter: Rakhesh
We're experiencing a *blocking hang* when calling {{setClientID()}} on a newly
created JMS connection. The call *never returns* and the thread remains stuck
in a {*}WAITING state{*}, with {*}no further AMQP activity observed{*}.
Repro code:
{code:java}
JmsConnection conn = (JmsConnection) factory.createConnection();
conn.setClientID("my-client-id"); // hangs indefinitely here{code}
Thread dump:
{code:java}
"custom-thread" #101
java.lang.Thread.State: WAITING (on object monitor)

h3. *Logs & Observations:*
* {{PN_TRACE_FRM=1}} is set — *only {{-> SASL}} frames are printed* repeatedly.
* No {{{}OPEN{}}}, {{{}BEGIN{}}}, or other frames are exchanged post-SASL.
* No logs from {{io.netty}} or {{org.apache.qpid}} even after setting level to
{{{}TRACE{}}}.
* Upgrading to {{2.7.0+}} doesn't resolve the issue either.
h3. *Expected Behavior:*
{{setClientID()}} should either:
* Complete successfully when broker responds
* Or fail with a timeout/error if handshake fails
h3. *Actual Behavior:*
* Hangs forever — appears to be waiting for a remote peer response that never
arrives.
* All consumer threads waiting on {{getConnectionPoolSize()}} also block due
to this.
