<p>genericInterfaces.length is not equal with interfaces.length. In detailed,</p>
<p>1) clazz.getGenericInterfaces() returns "interface java.io.Serializable" (1 element)<br/>
2) clazz.getInterfaces() returns "[interface java.io.Serializable, interface java.lang.Cloneable, <br/>
interface org.eclipse.persistence.internal.weaving.PersistenceWeaved, <br/>
interface org.eclipse.persistence.internal.descriptors.PersistenceObject, <br/>

interface org.eclipse.persistence.internal.weaving.PersistenceWeavedChangeTracking, <br/>
interface org.eclipse.persistence.internal.weaving.PersistenceWeavedRest]" (9 elements)</p>
<p>I do not confirm whether the issue is caused by @Embeddable which causes interfaces enhancements in runtime.</p>
<p>From the above result, I think that this issue is very important because this seemes to be relate with integration between cdi and jpa.</p>
<p>BTW: current glassfish uses Weld 2.0.0.Beta8, however, I believe that the issue will also happen on Weld core 2.0 master.</p>
<p>Thanks<br/>
