`AuthenticationInfo.requestAuthentication` uses separate `HashMap`'s `get`
+`put` calls.
Thread t, c;
c = Thread.currentThread();
if ((t = requests.get(key)) == null) {
requests.put (key, c);
assert cached == null;
return cached;
}
if (t == c) {
assert cached == null;
return cached;
}
Instead we can use the `HashMap.putIfAbsent` to make code a bit easier to
follow. We know that `requests` can contain only non-null values.
