Colin Werner created AMQ-9683:
---------------------------------
Summary: java.io.IOException on idle HTTP/XA connection
Key: AMQ-9683
URL: https://issues.apache.org/jira/browse/AMQ-9683
Project: ActiveMQ Classic
Issue Type: Bug
Components: JMS client
Affects Versions: 6.1.5
Reporter: Colin Werner
Similar config to https://issues.apache.org/jira/browse/AMQ-9682, but with
-Dorg.apache.activemq.SERIALIZABLE_PACKAGES=* and
--add-opens=java.base/java.util=ALL-UNNAMED set we able to run.
However, after a few minutes of idle we see the following stack trace:
{code:java}
09:14:21,811 [tp://localhost:61618] WARN .a.t.f.FailoverTransport - Transport
(http://localhost:61618) failed, attempting to automatically reconnect
java.io.IOException: Failed to perform GET on: http://localhost:61618 Reason:

I am not sure if this is the idle connection being dropped? I see nothing
strange in a wireshark pcap.
I tried to reproduce this in a unit test, but don't think I was able to set up
the exact same configuration, largely due to my lack of knowledge of the code
base. But I modified
https://github.com/apache/activemq/blob/main/activemq-http/src/test/java/org/apache/activemq/bugs/AMQ2764Test.java
to wait and eventually saw:
{code:java}
2025-03-11 16:39:16,175 [localhost:61616] - DEBUG HttpClientTransport
- Received null command from url: http://localhost:61616
2025-03-11 16:39:16,886 [localhost:61616] - DEBUG HttpClientTransport
- Received null command from url: http://localhost:61616 {code}
Which seems similar, but without a nasty stack trace.
