Type parameter names or wildcards are used as local variable type

[Marcono1234]

CFR version

0.149-SNAPSHOT (commit 06539a4)

Description

When decompiling methods which store the result of a generic method in a local variable and there is no further usage of this result, CFR emits the type parameter name or a wildcard, which is invalid code:

public static void main(String[] args) {
    ? o = GenericType.getWildcardInstance().doSomething();
    T o2 = GenericType.getInstance().doSomething();
    GenericType<T> o3 = GenericType.getInstance();
}

Also sorry for this flood of issues, I started poking at CFR a little bit. Let me know if they are too many or if you are not interested in these issues.

Example code

public interface GenericType<T> {
    T doSomething();
    
    static GenericType<?> getWildcardInstance() {
        return null;
    }
    
    static <T> GenericType<T> getInstance() {
        return null;
    }
    
    public static void main(String[] args) {
        Object o = getWildcardInstance().doSomething();
        Object o2 = getInstance().doSomething();
        Object o3 = getInstance();
    }
}
