%description
While Java is evolving and introduces new language features, the majority of
OSS libraries are still using Java 8 as their target because it still
dominates.

But, since most of features after Java 8 did not require a change in the
bytecode, javac could emit Java 8 bytecode even when compiling Java 12 sources.
