Alhambra is a project aimed at developing an open-source implementation of the next-generation Java virtual machine based on Oracle OpenJDK and the LLVM framework.
The goal of the project is to create a fast, easily portable just-in-time compiler for OpenJDK.
Currently, work is underway to support LLVM for OpenJDK version 11.
In 2020, a technical agreement was signed with Oracle Corporation for collaboration.
