Some more precisions, since this is a recurrent issue related in
Gilead forum :
- The offending annotation is *always* CascadeType. The code
source is the same as regular JPA annotation.
- Not a classpath issue : I repoduced the issue with the JAR on
classpath, and no way to tell Hosted Mode to take it into account
- Only the "embedded" hosted mode fails, web mode is ok.
