U8 (V8-based execution environment)
Since September 2018, Oracle has announced the licensing changes in Oracle JDK/OpenJDK. Summarizing them in short:
- If you are using Oracle JDK for any commercial/production (non-development) activity, you'll need a commercial license since day 1.
- If you are using OpenJDK (which is essentially equal to Oracle JDK in most development aspects), you'll continue to receive support and security updates for it, though Oracle will provide it only to the latest OpenJDK release.
- The typical release cycle for latest OpenJDK is one release per 6 months.
This ultimately means, that, to use any upstream Oracle-maintained JDK in production (and be sure it receives all up-to-date security update – what is a necessity for production usage), the users either have to purchase a commercial license; or use a free OpenJDK but necessarily upgrade to every new major release (and ensure all the software supports every new major release).
This adds unnecessary risks to any involved developments – including Universa project, where the main node codebase and the primary API is Java-based.
Also it effectively separates multiple aspects of codebase development:
- Performance-critical and networking code performed in C++ code layer;
The applications that may be running on U8 environment now or in future:
- Universa node implementation.
- Ubot server implementation.
- Parsec server.
- Any Universa clients or client-based software.
