-----------------------------------
Summary: lassCastException when using amqp-1-0-jms-0.24 client
Key: QPID-5417
URL: https://issues.apache.org/jira/browse/QPID-5417
Project: Qpid
Issue Type: Bug
Components: Java Client
Affects Versions: 0.24
Environment: qpid-cpp 0.24 broker with AMQP 1-0 support (via Proton
0.4) running on a CentOS 6.0 host. Client running on LinuxMint 15 Desktop
Reporter: Ulrich Romahn
Priority: Critical
I have installed a qpid-cpp broker (via source) on my CentOS machine and
successfully started.
I have then created a simple (but more extended) test application using the
amqp-1-0-jms client library.
I can successfully connect to an ActiveMQ 5.9 as well as a qpid-java 0.24
broker and exchange messages via a configured queue.
However, when I connect to my qpid-cpp broker (also 0.24 with proton 0.4), I
can send messages to a queue, but when trying to read from the queue I am
getting the following error message:
Exception in thread "Thread-7" java.lang.ClassCastException:
org.apache.qpid.amqp_1_0.type.Symbol cannot be cast to
org.apache.qpid.amqp_1_0.type.Section

Please note: I also re-compiled my test app using the latest 0.26-SNAPSHOT jms
client from source with the exact same error - in fact, the stack trace above
comes from this version, in case anybody was wondering.
Also, to verify my installations are all correct, I tried a similar test using
the Java example coming with qpid-proton 0.5 and could successfully connect and
exchange messages with any broker speaking AMQP 1-0 (qpid-cpp, qpid-java,
ActiveMQ, and Apache Apollo)!
I believe the issue is not actually in the subscriber, but in how the message
gets put into the queue.
I ran the following test as well:
1. I put a message into my queue using a simple test application with the
amqp-1-0-jms client library.
2. I then used the proton-j Recv.java test application to connect to this queue
(which is setup as "durable"). The proton-j 0.5 client now threw the exact same
ClassCastException.
