What the installer does

Windows

  • Delivered as a Windows Installer package built with WiX (.msi) for x64.
  • Installs for all users on the PC, which normally requires administrator rights.
  • No custom silent switch is declared; winget falls back to its default for this installer type (/quiet /norestart).
  • Associates with the file types .class, .jar, .java, and .jsp.
  • Adds the command-line commands jar, jarsigner, java, javac, javadoc, javap, javaw, jconsole, jdeprscan, and jdeps.
  • Shows up in Windows “Installed apps” as “Eclipse Temurin JDK with Hotspot 21.0.13+9 (x64)”.
  • Upgrades install over the existing version.

macOS

  • Delivered as a macOS installer package (.pkg) for Intel (x64) and Apple silicon (ARM64).
  • Runs the installer package OpenJDK21U-jdk_aarch64_mac_hotspot_21.0.13_9.pkg; package installers usually ask for an administrator password and can place files anywhere on the system.
  • On uninstall, Homebrew forgets installer package receipts.
