EnsureJavaVersionEvent

Gets fired when Minified is ensuring a valid java installation. Not fired if the requested Java version (or a higher compatible one) is already installed.

Fields

requestedMajorVersionint

The major Java version required to launch the game.

When it fires

JavaManager.ensureJavaVersion(requiredMajorVersion) first checks the JVM Minified itself is running on. If that JVM’s major version already satisfies requiredMajorVersion, this event never fires and the current JVM is reused to launch the game - no separate runtime is downloaded. It only fires once your running JVM is too old for the target Minecraft version, right before Minified looks for (or downloads) a matching managed runtime under its runtime install root.

Launcher.launchMinecraft(...) calls this indirectly via JavaManager.getRequiredJavaVersion(versionJson), unless you set LaunchConfiguration.customJavaExecutable - in that case Minified skips Java resolution entirely and none of the Java events fire.

Caution

This event (and JavaArchiveDownloadEvent / ExtractArchiveEvent) is posted to the EventBus passed to JavaManager.init(...), not automatically to LaunchConfiguration’s bus. See the Events introduction for how to share one bus across both.
