aldettinger opened a new issue #1605:
URL: https://github.com/apache/camel-quarkus/issues/1605
A camel-quarkus user could face a `ClassNotFoundException` when using
`onException` in native mode, for instance the following route :
```
onException(MyException.class).handled(true);
from("direct:onException").throwException(new MyException());
```
Could produce a stack trace similar as below:
```

I can't see any way to avoid loading the exception class during camel
`onException` handling.
I don't think we could register exception classes as reflective from an
extension without access to route definitions at build time.
So, at this stage, I'm thinking about documenting that when using
`onException(xxExceptionClass)`, then it's user's responsibility to register
`xxExceptionClass` for reflection.
