Applications that use Hibernate with cglib proxies fail to deploy due to java.lang.SecurityException

Applications that use Hibernate mapped to use cglib as its byte code provider will fail to deploy due to java.lang.SecurityException,

An example of the error message is:

Deployment "persistence.unit:unitName=lobtest.ear/lobtest-ejb-1.0-SNAPSHOT.jar#lobtest-jpa-jndi" is in error due to the following reason(s): java.lang.SecurityException: class "com.redhat.gss.lobtest.jpa.Item$$EnhancerByCGLIB$$defd1a7f"'s signer information does not match signer information of other classes in the same package

This happens because cglib.jar in EAP 5 is signed and the cglib-instrumented proxy uses the same signer information as cglib.jar, instead of the signer information for the applications target class.
