I'm trying to create a compositeusertype for an IP address I will store as a byte array in postgres. This is my first attempt at a user type, so I'm sure I'm just missing something obvious.

Let me simplify things a bit here and skip over some of the internals that were working just fine until I changed things from a plain class to a user type.

@Entity
@Table(name = "Device")
public class DeviceBean extends AbstractManagedEntity implements Device
{
...
private String name;
private IpAddress ip;
.....
}

public class IpAddress implements Comparable, CompositeUserType
{
private byte[] ip;
private String[] propertyNames = {"ip"};
private Type[] propertyTypes = {BinaryType.INSTANCE};

@Override
public String[] getPropertyNames() {
return(propertyNames);
}

@Override
public Type[] getPropertyTypes() {
return(propertyTypes);
}
// I implemented all the other required methods -- omitted for brevity.

@Override
public boolean isMutable() {
return false;
}

}

At runtime, here's my problem: isMutable is taken that there should be a property 'mutable' in my class.
