oscerd opened a new pull request, #25170:
URL: https://github.com/apache/camel/pull/25170
Child of CAMEL-24261 (completing CAMEL-23462 across the AWS2 producers).
## Problem
With `pojoRequest=true`, `MSK2Producer`'s `listClusters`, `createCluster`,
`deleteCluster` and `describeCluster` branches only acted when the body was
the
matching request type; any other body fell through the `instanceof` with no
`else`, so no AWS call was made, no response was set, and the original body
was
returned with no error.
## Fix
Each branch now throws `IllegalArgumentException` naming the required request
type, e.g.:
```java
} else {
throw new IllegalArgumentException(
"createCluster operation requires CreateClusterRequest in POJO
mode");
}
```
## Tests
Four tests in `MSKProducerTest` send a wrong-typed body to `pojoRequest=true`
routes (reusing the module's `AmazonMSKClientMock`) and assert the message.
Each
was verified to fail (silent no-op) before the fix — the `createCluster`
one, for
example, reports "Expecting code to raise a throwable" on `main`. Class
10/10 green.
These are hermetic unit tests against the in-JVM mock client (run
region-free) —
no localstack or real AWS.
## Docs / backport
The shared 4.22 upgrade-guide entry was added with CAMEL-24263. Main only,
matching
the CAMEL-23462 precedent (behaviour change, shipped in a minor, not
backported).
