java.lang.LinkageError: loader constraint violation error

I am getting this error in WildFly 8.2 at runtime:
java.lang.LinkageError: loader constraint violation: when resolving method "org.app.security.key.MyKeyRing.<init>(Lorg/app/security/key/MyPrivateKey;Lorg/app/security/key/MyPublicKey;[Ljava/security/cert/Certificate;)V" the class loader (instance of org/jboss/modules/ModuleClassLoader) of the current class, org/app/security/auth/KeyLoginModule, and the class loader (instance of org/jboss/modules/ModuleClassLoader) for resolved class, org/app/security/key/MyKeyRing, have different Class objects for the type curity/key/MyPrivateKey;Lorg/app/security/key/MyPublicKey;[Ljava/security/cert/Certificate;)V used in the signature
The classes starts with 'My' are created for the application and is inside the EAR file. There is a custom module in created in WildFly and the jar with these classes are available in that too.
What may be the reason?
Thanks!

JPA metamodel not recognized with Netbeans 7.4

I have a web application that is working fine under Netbeans 7.3. When I installed it on another computer with Netbeans 7.4, all references to the JPA metamodel are now undefined.
The import statements referring to the metamodel (those ending with an underscore, like the 3rd import statement below) are not recognized :
import bfMetier.ApplicationInitialise;
import entites.Locations;
import entites.Locations_;
And when I run the project, it aborts with a «cannot find symbol Locations_» error :
SEVERE: Exception while loading the app : EJB Container initialization error
java.lang.ExceptionInInitializerError
(...)
Caused by: java.lang.RuntimeException: Uncompilable source code - cannot find symbol
symbol: class Locations_
location: package entites
at beansFacades.LocationsFacade.<clinit>(LocationsFacade.java:10)
I'm using ecclipse as the JPA 2.0 provider and running the app under Glassfish 3.1.2.2.
Is there any parameter I need to add in order for the metamodel classes to be generated?
Thanks!
I created a new java project in 7.4 and found some differences...
There is no option in context menu for generating classes from database (like 7.3).
I found this option in New Java Class... Persistence category.
The entity generated by 7.4 do not have metadata classes.
Might be, the metadata classes are no longer generated/or needed by netbeans.
