[lworld] RFR: 8371356: [lworld] 'super' should be rejected in early construction context

[Vicente Romero]

There is a bug in the algo to determine what is kosher and what is not in early construction contexts. The algo was not analyzing any static symbol. But according to the `JLS 25 15.11.2 Accessing Superclass Members using super`:


It is a compile-time error if a field access expression using the keyword super
occurs in a static context (§8.1.3) or in an early construction context (§8.8.7) of
the current class.

the previous code was checking this only for instance field accesses. The current fix corrects this bug

TIA
