<p style='margin-top:0;margin-bottom:10px;'>I have a blob field that don't want updated when I do a save on other fields in the table. Hibernate seems to be doing an areEqual check despite the fact that I've designated the field as updatable=false. Because the field is lazy loaded it's null and I get a ClassCastException when it does the areEqual check on save. Why is it doing a compare on that field when it's not updatable?</p>
<p style='margin-top:0;margin-bottom:10px;'>So my field is designated as such:</p>
<p style='margin-top:0;margin-bottom:10px;'>@Basic(fetch = FetchType.LAZY)<br/>
@Column(<br/>
insertable = true,<br/>
updatable = false,<br/>
name = "documentData"<br/>
)<br/>
@Lob private Blob documentData;<br/>
On org.springframework.data.repository.CrudRepository.save() I get the following error:</p>
<p style='margin-top:0;margin-bottom:10px;'>java.lang.ClassCastException: org.hibernate.bytecode.instrumentation.spi.LazyPropertyInitializer$1 cannot be cast to java.sql.Blob<br/>
