[

]
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:
