BlobProxy (hibernate-core JavaDocs)

java.lang.Object
- org.hibernate.engine.jdbc.BlobProxy

All Implemented Interfaces:

java.lang.reflect.InvocationHandler
```
public class BlobProxy
extends java.lang.Object
implements java.lang.reflect.InvocationHandler
```
Manages aspects of proxying Blob references for non-contextual creation, including proxy creation and handling proxy invocations. We use proxies here solely to avoid JDBC version incompatibilities.
