turing85 opened a new issue, #4860:
URL: https://github.com/apache/camel-quarkus/issues/4860
# Bug description
Using `simple("${exchange.getMessage().getBody()}"` throws an exception at
runtime when compiling natively:
```
Caused by: org.apache.camel.component.bean.MethodNotFoundException: Method
with name: getMessage() not found on bean:
Exchange[ED6D02F79FBB419-0000000000000000] of type:
org.apache.camel.support.DefaultExchange on the exchange:
Exchange[ED6D02F79FBB419-0000000000000000]
...
```
# Affected versions:
Quarkus, at least from `2.13.x.Final` up to the current version
(`3.0.1.Final`).
# Reproducer:
- clone [this repository
(`github.com`)](https://github.com/turing85/camel-simple-language-bug):
```bash
git clone https://github.com/turing85/camel-simple-language-bug.git
cd camel-simple-language-bug
```
- Build the application:
```bash
./mvnw clean verify
```
- Observe that the tests pass:
```bash
...
[INFO] Tests run: 1, Failures: 0, Errors: 0, Skipped: 0
...
```
- Build the application natively:
```bash
./mvn --define native clean verify
```
- Observe that the tests fail with the above mentioned error in the
application log, and an unexpected status code on the tests, reporting a status
of `500` instead of the expected `200`:
```bash
...
Caused by: org.apache.camel.component.bean.MethodNotFoundException:
Method with name: getMessage() not found on bean:
Exchange[FD7D7D11C0B4B98-0000000000000000] of type:
org.apache.camel.support.DefaultExchange on the exchange:
Exchange[FD7D7D11C0B4B98-0000000000000000]
...
Expected status code <200> but was <500>.
...
```
# Workaround
Add the following to `application.yml`
```yaml
quarkus:
camel:
native:
reflection:
include-patterns:
- org.apache.camel.support.AbstractExchange
- org.apache.camel.support.MessageSupport
```
# Possible solution
The corresponding extension should register those classes for reflection by
default. This, however, begs the question: what else should be registered.
Thus, we should analyze all relevant classes used by the `simple(...)` language
and ensure that they all work as expected.
