Javax.persistence annotated class creating persistence.jar dependency

Question

Hi,
I'm trying to create a JAR for clients to use. I would like to include a few classes that have been annotated for use with hibernate using the standard javax.persistence annotations (code snippet below). The problem is, @GeneratedValue accepts a javax.persistence.GenerationType enum which is creating a dependency and, in fact, causes the client's compiler to fail if they try to import and use the Award class after including my JAR.
Does anyone know of a solution. Thanks in advance. Here's the compiler output:
An exception has occurred in the compiler (1.6.0_04). Please file a bug at the Java Developer Connection (http://java.sun.com/webapps/bugreport)  after checking the Bug Parade for duplicates. Include your program and the following diagnostic in your report.  Thank you.
com.sun.tools.javac.code.Symbol$CompletionFailure: class file for javax.persistence.GenerationType not found

@Entity
@Table( name = "award" )
public class Award
    @Id
    @GeneratedValue( strategy = GenerationType.IDENTITY ) // this requires that GenerationType be available to the client
    @Column( name = "award_id", nullable = false, length = 19 )
    private Long id;
    // etc., etc.
}

Did you read the error message anyway? Did you bother to Google the error message?
At least try upgrading both the JDK and the JPA implementation.
