Enums are not desugared since Java 15

[Marcono1234]

CFR version

bc8d9a2

Compiler

javac 16

Description

Sine Java 15 enums have a method $values() which creates the array containing the enum constants, see JDK-8241798.

This causes CFR's EnumClassRewriter to consider the enum to be malformed and prevents it from desugaring it.

Example

Any enum compiled with Java >= 15 should allow reproducing this, e.g.:

enum EnumTest {
    A,
    B;
}
