8371382: [lworld] Javac accepts field initializer that refers to a superclass field

[vicente-romero-oracle]

Javac is accepting this code:

abstract value class ValueParent {
    int b = 5;
}

value class ValueClass extends ValueParent {
    int a = b;
}

This is not allowed as in value classes field initializers will run in the prologue phase where references to super class fields are forbidden

TIA

Looks reasonable

Looks reasonable

thanks for the review

[vicente-romero-oracle]

it is OK for a field with initializer to refer to another field with initializer, so no warning or error if we are analyzing a field initializer
