Possible disadvantages of Zulu

    While Zulu is open source, understanding and navigating the various licensing options for commercial services might be complex for some users.
  • Dependency on Azul's Ecosystem
    Leveraging additional features and tooling often ties users into Azul's ecosystem, which may not be ideal for those seeking completely independent solutions.
  • Potential Overhead for Small Projects
    For very small projects or startups, the commercial support and additional features might be more than what is needed, leading to unnecessary overhead.
  • Java Version Compatibility
    While Zulu supports many platforms, users need to ensure compatibility with specific Java versions required by their applications, which can occasionally be an issue.

    While community support is strong, official support and services, which might be required by enterprise environments, are often provided by third parties and may come with additional costs.
  • Patch Availability
    Security patches and updates may not be rolled out as quickly in some OpenJDK distributions compared to Oracle's commercial JDK.

  • Lisp Virtual Machine Design Question
    Reloading is nothing new under the sun for Lisp, I believe. For ML and adequate reload-ability, one might be hard pressed, but it's nothing new under the Sun (hint, hint). Maybe too on the nose, but one probably wants good inlining, and thus more "speculative" de/optimisation to preserve redefinition. Source: over 2 years ago
