@Enumerated doesn't work on fields

I can't claim to be an expert on the JPA spec, but I've at least seen examples implying that @Enumerated(EnumType.STRING) should work on the field level in addition to the getter. SimpleJPA only works on the getter.  Don't get me wrong, I'm glad there's a fix to my pain, but shouldn't this annotation also work at the field level? 

Thanks - this is an excellent tool you've developed!
