[hibernate-issues] [Hibernate-JIRA] Commented: (METAGEN-37) MappedSuperclass with type parameters result in uncompilable metamodels

[Hardy Ferentschik (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/METAGEN-37?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=38611#action_38611 ] 

Hardy Ferentschik commented on METAGEN-37:
------------------------------------------

Seems {{TypeUtils.extractClosestRealTypeAsString()}} is doing this wrong thing. Currently the generated AttachmentGroup_ is:

{code}
package org.hibernate.jpamodelgen.test.typedmappedsuperclass;

import javax.persistence.metamodel.SetAttribute;
import javax.persistence.metamodel.SingularAttribute;
import javax.persistence.metamodel.StaticMetamodel;

@StaticMetamodel(AttachmentGroup.class)
public abstract class AttachmentGroup_ {

        public static volatile SingularAttribute<AttachmentGroup, Long> id;
        public static volatile SetAttribute<AttachmentGroup, Post<UserRoleType>> posts;

}
{code}

It really should be:
{code}
package org.hibernate.jpamodelgen.test.typedmappedsuperclass;

import javax.persistence.metamodel.SetAttribute;
import javax.persistence.metamodel.SingularAttribute;
import javax.persistence.metamodel.StaticMetamodel;

@StaticMetamodel(AttachmentGroup.class)
public abstract class AttachmentGroup_ {

        public static volatile SingularAttribute<AttachmentGroup, Long> id;
        public static volatile SetAttribute<AttachmentGroup, AttachmentGroupPost> posts;

}
{code}

Correct? WDYT?

> The attached tgz illustrates the bug, run mvn compile.  The metamodel for the base class either needs a type param (and likewise the extends class on the sub-metamodel), or the base class needs to be generated with Object as the type
