FailsafeCall micro refactoring, plus World-Wide Nr.1 duplicated utility method for OkHttp

As you can see here:

FailsafeCall micro refactoring:

1. AtomicBoolean fields are final

2. lambda expression instead of code block

3. World-Wide Nr.1 duplicated utility method for OkHttp
   `/** [OkHttp Callback to JDK CompletableFuture]
   
   Helps eliminate dozens of utility classes World-wide with exactly this same method.
   
   Can be the first small step towards FailSafe.
   
   Returns normal JDK {@link CompletableFuture} without FailSafe policies.
   */

public static CompletableFuture asPromise (okhttp3.Call call)`

All around the World, people write this method again and again. I have done it too.
We really need "The Chosen One". I recommend you to be this one :-)

If you like it, I will send it as PR.

OK

2. lambda expression instead of code block

Aren't those braces ignored, anyway? It's just a single expression. (The indenting of the modified code is off, btw.)

Does this utility belong in FailsafeCall.java? If included at all, wouldn't it be better as a single static method in a utility class?

IntelliJ IDEA's work :-)

As I know, the resulting byte code is the same.

To be honest, not 100%... but I really want to drop such "one method utility class" in my codebase.
And I don't like to add new dependencies. Failsafe have managed after long testing, etc.

🙏

If you do some research in Internet, you will find that people reinvent this wheel over and over, write almost the same method over and over.
We must protect the Earth from global warming! :-)

As a small sign of gratitude, I won't then write an issue about a large PR to concurrentunit (Excellent library BTW)

Your wish is my command. Tell me if I should send an PR.

Not up to me.
