Notes for myself:<br /><br />CollectionBinder#bind had a relevant fix commented out -- switched it to the following:<br />{code}<br /> // do it right away, otherwise @ManyToOne on composite element call addSecondPass<br /> // and raise a ConcurrentModificationException<br /> sp.doSecondPass( CollectionHelper.EMPTY_MAP );<br />// mappings.addSecondPass( sp, !isMappedBy );<br />{code}<br /><br />Your entities had the following, causing the issue:<br />{code}<br />User<br /> @ElementCollection(fetch = FetchType.EAGER)<br /> private Set<Address> addresses;<br /> <br />Address<br /> @ElementCollection(fetch = FetchType.EAGER)<br /> @Enumerated(EnumType.STRING)<br /> private Set<AddressType> type;<br />{code}<br /><br />Un-commenting that fix results in an exception at the following stack.
