Is it possible to modify mapping for @Column() during runtime?

I have some entity mapped to a sql view as

@Entity
@Immutable
@Table(name = "SOME_VIEW")
public class MyClass implements Serializable {

 @Id
 @Column(name = "SOME_COL", insertable = false, updatable = false)
 private Integer id;
 ...
}

Today I was told that on one one of servers, column SOME_COL in SOME_VIEW will be filled with nulls, and I should use SOME_OTHER_COL as id, depending on value in config.properties file. Since @Column has @Retention(RUNTIME), might it be possible that I can change mapping to @Column(name = "SOME_OTHER_COL") before application starts on tomcat?
