#1307 False positive: SingularField and lambda-expression

[PJ Walstroem]

package com.foo;

import java.util.Optional;

public enum Supplier {
    bar("Bar"),

    private final String supplierName;

    private Supplier(String supplierName) {
        this.supplierName = supplierName;
    }

    public static String getSupplierNameIfPresent(String supplier) {
        return Optional.ofNullable(supplier).map(foo -> valueOf(supplier).supplierName).orElse("");
    }
}

[PJ Walstroem]

violates SingularField:
"Perhaps 'supplierName' could be replaced by a local variable."

Will be fixed with the next version.
