[hibernate-issues] [Hibernate-JIRA] Commented: (METAGEN-33) Metamodel is not generated with @Generated annotation

Hardy Ferentschik commented on METAGEN-33:
------------------------------------------

It seems Eclipse is depending on an optional feature. AFAIU @Generated is optional. The problem with adding it to the static metamodel is that @Generated was added only in Java 6. This means a meta model containing @Generated will not work in a Java 5 JVM which seems to be an unnecessary restriction. 
We could introduce a flag to the processor which when enabled adds @Generated to the metamodel classes. This way it is up to the user to decide whether the code should be able to run in a Java 5 JVM.

> The static meta model does not have a @Generated. This is probably the reason that avoids Eclipse compiling  of the derived classes (we must clean the project, or alter the generated class and save it). The eclipselink metamodel generator works fine, and the only difference between EclipseLink generator and hibernate generator is this annotation
