🛠️OpenJDK Deprecates macOS/x64 Port for JDK 27
macOS/x64 OpenJDK port is on its way out, what now?
TL;DR
The macOS/x64 port of OpenJDK will be deprecated with JDK 27. Oracle engineers will stop maintaining it as Apple transitions to AArch64 architecture, leaving developers with limited options moving forward.
OpenJDK is deprecating its macOS/x64 port for JDK 27, signaling a shift in support towards Apple's new AArch64 processor architecture. This move affects any developer currently using or planning to use OpenJDK on macOS systems. Starting with JDK 27, the macOS/x64 port will no longer be maintained by Oracle engineers and may not build or function properly after deprecation. Developers can still configure a deprecated port using --enable-deprecated-ports but should expect issues down the line. The decision to phase out support is driven by Apple's transition away from x64, making it crucial for developers to plan their migration.
Key Points
macOS/x64 port deprecation starts with JDK 27 release, Oracle's last maintenance cycle
Apple transitions to AArch64 architecture, phasing out x64 support in macOS systems
Build performance for deprecated ports: cores used - 32, memory limit - 96601 MB
GitHub actions in OpenJDK repository will disable the macOS/x64 port by default post-JDK 27
Port-specific features noted as deprecated for removal in relevant JDK documentation
Why It Matters
If you're running Java applications on macOS with x64 architecture, your days are numbered. Starting JDK 27, Oracle will no longer maintain the macOS/x64 port of OpenJDK. This shift impacts developers who rely on this setup for their projects. Transitioning to AArch64 or finding an alternative solution is now a priority.
