Josh Long opened SPR-11807 and commented
In the example below, I define an aspect which I expect to be applied to all beans of type CommandLineRunner, it isn't if the bean is defined as a lambda on java version "1.8.0_05" on OSX.
(java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode))

@Bean
CommandLineRunner bad() {
return (args) -> System.out.println(String.join(",", args));
}
public static void main(String[] args) throws Exception {
ApplicationContext applicationContext = new AnnotationConfigApplicationContext(Application.class);
applicationContext.getBeansOfType(CommandLineRunner.class).forEach((k, v) -> System.out.println(k + '=' + v));
for (int i = 0; i < 4; i++) {
applicationContext.getBeansOfType(CommandLineRunner.class).forEach((k, v) -> {
try {
v.run(args);
} catch (Exception e) {
e.printStackTrace();
}
