I have a problem with hibernate and MySQL and inserting a blob.

In our previous version of hibernate (3.6.0) a blob was persisted to the database
with BlobTypeDescriptor.STREAM_BINDING.
Now the blob is persisted with BlobTypeDescriptor.PRIMITIVE_ARRAY_BINDING.
(see org.hibernate.type.descriptor.sql.BlobTypeDescriptor.DEFAULT and the doBind method)

The latter uses twice (2x!) the number of bytes (I think a byte is encoded as hex) as the streaming option.
In our junittest we now get the exception "com.mysql.cj.jdbc.exceptions.PacketTooBigException"

I noticed that the problem doesn't exist for Clob. A provision for Clob is made in org.hibernate.dialect.Dialect.
I think the same provision should be made for Blob.

In Dialect.java the following code is in method Dialect.getSqlTypeDescriptorOverride(int sqlCode):

	protected SqlTypeDescriptor getSqlTypeDescriptorOverride(int sqlCode) {
		SqlTypeDescriptor descriptor;
		switch ( sqlCode ) {
			case Types.CLOB: {
				descriptor = useInputStreamToInsertBlob() ? ClobTypeDescriptor.STREAM_BINDING : null;
				break;
			}
			default: {
				descriptor = null;
				break;
			}
		}
		return descriptor;
	}

The method could be changed to:

	protected SqlTypeDescriptor getSqlTypeDescriptorOverride(int sqlCode) {
		SqlTypeDescriptor descriptor;
		switch ( sqlCode ) {
			case Types.CLOB: {
				descriptor = useInputStreamToInsertBlob() ? ClobTypeDescriptor.STREAM_BINDING : null;
				break;
			}
			case Types.BLOB: {
				descriptor = useInputStreamToInsertBlob() ? BlobTypeDescriptor.STREAM_BINDING : null;
				break;
			}
			default: {
				descriptor = null;
				break;
			}
		}
		return descriptor;
	}
