Attribute not generated for Blob type fields
--------------------------------------------

                 Key: METAGEN-38
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/METAGEN-38
             Project: Hibernate Metamodel Generator
          Issue Type: Bug
    Affects Versions: 1.0.0-CR-1
         Environment: Hibernate 3.5.3-Final, Oracle DB
            Reporter: Stu White

Hi,

I've got a class with a field of type java.sql.Blob, and it appears that the Hibernate Metamodel generator is ignoring this field when generating the metamodel. Other fields are generated correctly.

The class in question looks like:

{code:title=BlobEntity.java|borderStyle=solid}
@Entity
@Table(name = "BlobEntity", schema = "Repository")
public class BlobEntity
{   
    @Id
    @Column(name = "blob_id")
    private String mId;
    
    @Lob
    @Column(name = "blob_value", insertable = false, updatable = false)
    private Blob mBlob;

    /// Etc
{code}
The generated metamodel looks like:

{code:title=BlobEntity_.java|borderStyle=solid}
@StaticMetamodel(BlobEntity.class)
public abstract class BlobEntity_ {

    public static volatile SingularAttribute<BlobEntity, String> mId;

}
{code}

Admittedly, generating an attribute for a Blob field isn't particularly useful because we don't want to search against this field. However, Hibernate seems to generates a warning about this missing field ("Unable to locate static metamodel field ... ") at startup, and spec (http://docs.jboss.org/hibernate/jpamodelgen/1.0/reference/en-US/html_single/) seems to suggest that a field should be generated.

I've attached a test case to reproduce, but it's pretty trivial. If you need any further information or if there's anything I can do then please let me know.
