This thing is a-ma-zing. It is truly a wonder. It is something to behold. The "Disruptor" pattern.-

Agentically convert to rust, get more trades faster

the long pause is the JVM starting up

Oh, I see, jokes from 30 years ago!

And still funny today, not all jokes survive that long.

Alternatively:

Knock, knock

who's there

It's the 90s, wanting their jokes back

Why do they want the jokes back?

The long pause between the knock and the answer took 30 years

What else are you supposed when keeping up with platforms proves too difficult!

G1 is now the default garbage collector in 27.

Sorry I only just set -xXx360NoScopexXx=4G to run that latest version without hitting OOM and you are right, it is indeed quite fast with G1.

You misunderstand, xxx360NoScopexxx is now the default.

If I'm not mistaken, OpenJ9 runtime offers some kind of precompilation and fast startup.

Don't put a 30gb heap on m4 boxes and you'll be okay

*OOM-kills 20 other programs on your PC while booting up*

It's on you bc it was (arguably but still) dead 17 years ago.

edit: don't get me wrong, i am not here to hate java, but bc i am also ... hm necrophil :)

17 years is a rookie number. Take C# auto-properties, for example: 19 years ago!

Now try asking, "When did Java get auto-properties?"

News at 11.

Language that runs on the explicit design philosophy of letting other languages experiment first and then incorporating their lessons learned once the dust has settled is late to implement a feature.

I never cared about those kind of syntax sugars. I was happy with IDE/static checkers, lombok, mapstruct, etc.

I missed generators like that virtual threading for example.

btw: i was referring a single point when oracle bought sun and "closed java".
