> 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.
