IcedTea-Web open-source project

The IcedTea-Web open-source project, stewarded by Azul Systems, maintains the reference implementation of the Java Web Start and Java Plug-In standards that were deprecated by Oracle after Java 9. Focused on enterprises that still rely on browser-launched or auto-updating Java applications, the project compiles and redistributes the IcedTea-Web codebase as thoroughly tested, OpenJDK-compatible installers for Windows, Linux, and macOS. Typical use cases include launching legacy ERP dashboards, remote-access consoles, engineering applets, and government forms that expect to be invoked from a hyperlink or desktop shortcut and then cache themselves locally while respecting sandbox rules and corporate proxy settings. Because Azul’s builds are built against its own Zulu and Zulu Prime JVMs, they integrate cleanly with existing Java 8, 11, or 17 deployments without recompiling or repackaging the underlying JNLP files. Administrators can therefore prolong the life of line-of-business tools while migrating the runtime to a supported, security-patched stack. IcedTea-Web software is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always fetch the latest upstream release, and can be installed alongside other applications in a single batch operation.
