>         Environment: Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_05-b05)

> I'm doing absolutely vanilla versioning, using an int version, and setVersion(int)/getVersion():int accessors.
> *But* one of my persistent classes had a setVersion(String) accessor (a NOP) that I left in for backwards compatibility with objects stored by XMLEncoder that I import with XMLDecoder.
> Having setVersion(String) stops XMLDecoder from complaining that it can't find the method. The method itself does nothing.
> THE PROBLEM: The presence of setVersion(String) confuses Hibernate when I save the persistent object. It ignores the setVersion(int) and tries to call setVersion(String), which yields a "BasicPropertyAccessor ERROR - IllegalArgumentException".
> Here are the essentials:
> ----------------------------------------
> public abstract class Entity {
> 	private Long id;
> 	private int version;
> 	public Long getId() {
> 		return id;
> 	}
> 	public void setId(Long anId) {
> 		id = anId;
> 	}
> 	public int getVersion() {
> 		return version;
> 	}
> 	public void setVersion(int aVersion) {
> 		version = aVersion;
> 	}
> }
> public class Template extends Entity {
> 	public void setVersion(String aVersion) {
> 		// NOP
> 	}
> 	...
> }
> <class name="Template" table="`TMPL`">
> 	<id name="id" column="`TMPL_ID`">
> 		<generator class="native"/>
> 	</id>
> 	<version name="version" column="`VER`"/>
> 	...
> </class>
> BasicPropertyAccessor ERROR - IllegalArgumentException in class: mypackage.Template, setter method of property: version
> BasicPropertyAccessor ERROR - expected type: java.lang.String, actual value: java.lang.Integer
> AbstractFlushingEventListener ERROR - Could not synchronize database state with session
> org.hibernate.PropertyAccessException: IllegalArgumentException occurred while calling setter of mypackage.Template.version
