Wie Roboter tröten (2)

Im letzten Beitrag wurde ein erster Bot für Mastodon erstellt. Der Bot postet mittlerweile drei mal täglich um 8:00, 12:00 und 16:00 Uhr ein englischsprachiges Zitat auf Mastodon. Obwohl die Anwendung schon hinreichend arbeitet, fehlen noch Kleinigkeiten zum dauerhaften Einsatz.

That's all there is to it once you are past #Java 9.
Migration from #Java11 to #Java17.

I haven't even really started using Java 11 APIs =)

So yes, it turns out that though our communication partner pretends to accept HTTP/2, their API server adheres to HTTP/1.1 standards. And with HTTP/1.1, the #Java11 #HttpClient will send a #ContentLength header even if the payload is 0 bytes. Which is exactly what our communication partner expects. A bit weird, and sad.

It looks like #Java11 decided to completely omit the #contentLength header of an #HttpPost request if the content length equals 0 (zero). That's possible with HTTP/2, but not with HTTP/1.0 or 1.1.

The #RESTAPI server we talk to requires a content-length header even if the payload is empty. Does downgrading to HTTP/1.1 change the behavior of #JavaNetHttp? Does that get the header included?

Or do we have to override default header filtering?

#Enterprise #Message #Queues require a different mindset than batchwise #processing. With an #EMQ one gets nudged to handle 1 message at a time. It needs #software #languages that have quick start-up times. Historically, #Java has a bad rep for that.

With #Java11 and IBM
's #OJ9 the cold-start speed of a program can be greatly increased (vs Oracle
's #Hotspot) to the point where the program no longer needs to run forever... which is why we can use it on #AwsLambda with #Kafka.

The other day I learned that the #javaNetHttpClient should be cached and reused. It doesn't really matter if you have 1 or 2 calls. It does matter if you have thousands.

This client became available with #Java11.

The problem is lingering opened sockets, waiting for a response from the communication partner. They cost memory and system resources. Reusing the #HttpClient allows it to streamline itself.

So, 62% indicated "no prio from PO / business" as a reason not to migrate to #java11.

Unpopular opinion: assuming you WANT to migrate, aren't WE, the developers, at fault here, failing to bring up sufficient arguments to the PO as to why this should be done in the first place? https://twitter.com/MichelSchudel/status/1262997139933839360

Last week I migrated one of my #dataIntegration #software applications. It went from #XML input and #JSON output to JSON input and output, and at the same time from #Oracle #Java8 to #IBM #Java11.

That move cut away 2/3rds of the #sourceCode.

The functionality stayed roughly the same. Some validations got omitted. I may wind up adding them back in.

This is the way forward. It wouldn't have been possible without tooling that produces JSON documents. #OpenText #BizMapper

👍 TV-Browser 4.2 Final

📌 Heute veröffentlichen wir TV-Browser 4.2. Die Veröffentlichung hat diesmal etwas länger gedauert, da durch den Wechsel auf Java 11 längere Tests nötig waren, um sicher zu stellen, dass TV-Browser stabil läuft.

See, in #java all data types that aren't primitives inherit from the Object class. And that means that any process could generate an Object #array as its return value. It would be a single compound value, the elements of which can be accessed by index.

Up until #java11 however, if we were to access those elements, we were responsible for telling the compiler what #dataType we expected, and we would have to perform a type cast.

And the compiler couldn't check for type safety.

The #SDKMan web team over at the bird site announced that they'll be distributing #OpenJ9 #Java11 #SDK. I haven't seen it at their web site yet: https://sdkman.io/
but they say you can install it like so:
`sdk i java 11.0.2.j9-adpt`
