Microsoft’s Java Engineering Group has reported progress in porting OpenJDK, or open source Java, to Windows 10 on ARM64-based devices, having completed the first phase of the initiative in late June. The company’s initial changes are being upstreamed to the OpenJDK project itself.
The port has been submitted to OpenJDK in partnership with Red Hat. An early access binary is available via GitHub. Microsoft said it has seen increased adoption of ARM64 on laptops and servers, with the architecture offering higher energy efficiency in data centers and battery life extension on personal devices.
