Thank you for creating this package @micycle 🙂

I tried to use your latest release (4.1.1) on an Intel Mac. It works in Java2D mode but crashes with P2D using an empty sketch that just calls `size()`.

Do you know why this could be?

**Update** : maybe it’s the JDK, as mentioned in [How to make 3D with Processing core library - #6 by matthewortega](https://discourse.processing.org/t/how-to-make-3d-with-processing-core-library/19710/6)

**Update** : I made it work by doing two things:

1. Added this to the `build.gradle.kts` file

```plaintext
java {
    toolchain {
        languageVersion.set(JavaLanguageVersion.of(17))
        vendor.set(JvmVendorSpec.ADOPTIUM)
    }
}

```

1. On the command line I install this Java JDK

```auto
brew install --cask temurin

```
