    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-5712?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=39601#action_39601 ] 

Jerome commented on HHH-5712:
-----------------------------

I have the same problem with this mapping

    @ManyToMany(fetch = FetchType.LAZY, targetEntity = AbstractBlock.class)
    @JoinTable(
        name="B_WEBLOCK_COLUMN",
        joinColumns=@JoinColumn(name="WEBBLOCK_ID"),
        inverseJoinColumns=@JoinColumn(name="WEBBLOCK_SLAVE_ID")
    )
    List<? extends AbstractBlock> blocks = new ArrayList<AbstractBlock>(0);


with this exception

org.hibernate.annotations.common.AssertionFailure: Fail to process type argument in a generic declaration. Member : eu.ttbox.model.ui.store.fragment.BlockColumn#blocks Type: class sun.reflect.generics.reflectiveObjects.WildcardTypeImpl
        at org.hibernate.ejb.metamodel.AttributeFactory$PluralAttributeMetadataImpl.getClassFromGenericArgument(AttributeFactory.java:846)  - [na:na]
