Review Creating your first Micronaut app

[gijsleussink]

While reviewing the Maven/Java guide, I noticed the steps to generate a native image with GraalVM include an example of installing 21.2.0.r8 (sdk install java 21.2.0.r8-grl), but Java 8 support isn't provided (through SDKMan) anymore.

Reviewing done ✅

When 21.2 was first released only v11 was supported by SDKMan, but they added v8 and v16. This is the GraalVM output I get when I run sdk list java:

 GraalVM       |     | 21.2.0.r16   | grl     |            | 21.2.0.r16-grl
               |     | 21.2.0.r11   | grl     | installed  | 21.2.0.r11-grl
               |     | 21.2.0.r8    | grl     |            | 21.2.0.r8-grl
               |     | 21.1.0.r11   | grl     | local only | 21.1.0.r11-grl
               |     | 21.1.0.r8    | grl     | installed  | 21.1.0.r8-grl
               |     | 20.3.3.r11   | grl     |            | 20.3.3.r11-grl
               |     | 20.3.3.r8    | grl     |            | 20.3.3.r8-grl
               |     | 20.3.2.r8    | grl     |            | 20.3.2.r8-grl
               |     | 19.3.6.r11   | grl     |            | 19.3.6.r11-grl
               |     | 19.3.6.r8    | grl     |            | 19.3.6.r8-grl

Exactly what Burt said. They first released GraalVM for JDK11 on July 20th (as scheduled) and a week later they released it for JDK 8 and 16.

@gijsleussink try running sdk update

[burtbeckwith]

I see what's happening - there's no 21.2.0 for JDK 8 on Mac, see https://github.com/graalvm/graalvm-ce-builds/releases/tag/vm-21.2.0
Ivan and I use Linux, so it shows up for us

🐧 FTW!
