Question

So I have saved a JDO entity that contains an value of MyEnum.

public enum MyEnum {
    MyValue1,
    MyValue2,
    MyValue3;
}

However now I need to remove at least one of the enum values. Will this crash JDO queries since a value that has been stored is no longer valid?

Thanks for the help.

Answer 1

JDO most probably uses Enum.valueOf(class, string) to instantiate enums. So in case of unsupported values it will produce IllegalArgumentException.
