---------------------------------------
Summary: LangChain4jEmbeddingsComponentInfinispanTargetIT is flaky
due to Infinispan Hot Rod connection timeout
Key: CAMEL-23253
URL: https://issues.apache.org/jira/browse/CAMEL-23253
Project: Camel
Issue Type: Bug
Components: camel-langchain4j-embeddings
Reporter: Guillaume Nodet
The integration test {{LangChain4jEmbeddingsComponentInfinispanTargetIT}} in
{{camel-langchain4j-embeddings}} is flaky on CI. It fails intermittently with
an Infinispan Hot Rod {{SocketTimeoutException}} (2000ms timeout) when trying
to connect to the testcontainer.
The failure cascade:
# {{CachePingOperation}} times out after 2000ms connecting to Infinispan
# {{FailedToStartRouteException}} is thrown because the route cannot start
# Subsequent test methods fail with {{RejectedExecutionException: CamelContext
is stopped}}
Stack trace:
{code}
org.apache.camel.FailedToStartRouteException: Failed to start route: route1
because: org.infinispan.client.hotrod.exceptions.TransportException::
java.net.SocketTimeoutException:
RetryingHotRodOperation{delegate=CachePingOperation{___protobuf_metadata,
flags=0}...} timed out after 2000 ms
{code}
Observed on JDK 25 CI build for PR #21994
([run|https://github.com/apache/camel/actions/runs/23535611086/job/68552019353]).
JDK 17 and JDK 21 builds passed.
Possible fixes:
* Increase the Hot Rod client connection timeout for the test
* Add retry logic for the testcontainer readiness check
* Add {{@Timeout}} or conditional skip when the container is not ready
