JavaCompiler API 的内存编译优化用例

用法

String lambdaSource = """
        import java.util.function.BiFunction;
        public class LambdaContainer {
            public static BiFunction<Integer, Integer, Integer> getLambda() {
                return (x, y) -> x + y;
            }
        }
        """;

CompilationResult compile = JavaCompiler.NATIVE.compile("LambdaContainer.java", lambdaSource);
