Type: Bug
Resolution: Unresolved
Priority: Major
Fix Version/s: 4.2.x, 4.3.x, 4.30.x
Affects Version/s: 4.1.0.Final
Component/s: hibernate
Labels:
None
Environment:

Ubuntu 13.10 64-bit, Intel i-7, 4GB RAM

Steps to Reproduce:

Hide

On our project, if we add the annotation @ElementCollection on any Entity, eclipse got random errors on entities that not exists, because project runs without problem, if we remove the annotation @ElementCollection the errors disappear.

Examples:
On @Entity annotation the error is: "Name is Empty"

On @ManyToMany the error is: "The attribute type for a collection mapping must be java.util.Collection, java.util.Set, java.util.List or java.util.Map"
