If you also care for constant lambda, this could be optimized even further, but for the price of more complex code:

NamedPackage p = packages.get(name);

    Package pkg = NamedPackage.toPackage(name, m);
    p = packages.putIfAbsent(name, pkg);
    if (p == null) {
        return pkg;
    }

return (Package)packages.compute((n, p) -> {

    return (Package)packages.compute(name, (n, p) -> {

assert p != null;
    // replace NamedPackage with Package

return (p instanceof Package) ? p : NamedPackage.toPackage(p.name(), p.module()); });
