valhalla-docs VS adoptium

What isn't clear for me from https://github.com/openjdk/valhalla-docs/blob/main/site/design-notes/state-of-valhalla/02-object-model.md is whether or not value types will indeed be headerless.

Regarding type erasure, see https://github.com/openjdk/valhalla-docs/blob/main/site/design-notes/in-defense-of-erasure.md for a justification. Note in particular that not doing erasure would have forced languages like Scala to follow Java's semantics. In cases where erasure is actually a problem, you can work around it with classes like https://fasterxml.github.io/jackson-core/javadoc/2.2.0/com/fasterxml/jackson/core/type/TypeReference.html.

Here's a (relatively recent) post on type erasure from the lead of the value types project at Oracle https://github.com/openjdk/valhalla-docs/blob/main/site/design-notes/in-defense-of-erasure.md

If you want to read something a little more formal and fleshed out, try scanning through this document, and then come back again and tell me that Brian doesn't understand your suggestion.

I haven't been following it incredibly closely, but I have checked in from time to time. It's a hard problem, but there's a lot of real progress (https://github.com/openjdk/valhalla-docs/blob/main/site/desi...).

I'd wager that it will ship by the next LTS, in 2024.

Quotes from here

Used the recommended JRT https://adoptium.net/

Wandered through the https://github.com/hneemann/Digital site and saw past issues with JRT but no obvious solution.

I have a couple hundred GALs of same or similar model number of new old stock

Oracle Java is shit use https://adoptium.net/ or another one

Some options for those who prefer to avoid the Oracle minefield:

https://adoptium.net

https://aws.amazon.com/corretto

Sadly, no-one has managed to package it yet, but we should get something in the next couple of days. Since 21 is an "LTS" release, major Linux distributions will provide a runtime pretty soon. Ubuntu backports them to old releases too.

https://adoptium.net/ This link?

I'm using this one on MultiMC. https://adoptium.net/

some of these will take care of java for you, others are more manual. if you need java, I recommend https://adoptium.net/

You can totally use VSCode. It's Java support is quite good (it really uses Eclipse under the hood basically). You can compile Java code by hand if you install the Java Development Kit. You can also use a build tool to help you. Maven is the most used one. It has a bit of a learning curve but makes using libraries a lot easier.
