Carsten Hoehne commented on JBIDE-1768:
---------------------------------------

Vacation ended. So i tested your result.zip.

With your mapping:
	@CollectionOfElements(fetch = FetchType.EAGER)
	@JoinTable(name = "samplewell", joinColumns = { @JoinColumn(name = "SAMPLE2WELLID", nullable = false, updatable = false) }, inverseJoinColumns = {
			@JoinColumn(name = "SAMPLEID", updatable = false),
			@JoinColumn(name = "well_adress", updatable = false),
			@JoinColumn(name = "well_column", updatable = false),
			@JoinColumn(name = "well_row", updatable = false) })
	@Cascade( { CascadeType.SAVE_UPDATE })
an exception (saying that inverseJoinColumn targets an unmapped Class - which is correct) is thrown whilst deploying.
d
If inverseJoinColumns is deleted it is deployed with this exception:
javax.persistence.PersistenceException: org.hibernate.HibernateException: cannot simultaneously fetch multiple bags

I do not know the exact point where the exception is raised. I have to debug.
The app with hbm.xml mappings and without Entitymanager deploys successfully.
This new Hibernate/JPA app with Entitymanager does not deploy. But i suppose that this has nothing to do with this issue.
So this issue can be closed when inversejoincolumn is removed. 

After hunting down the remaining problems i will eventually a new issue.
