[FELIX-4480] should ignore inner classes that are created within static methods

• Type: Bug
• Status: Closed
• Priority: Major
• Resolution: Invalid
• Affects Version/s: ipojo-manipulator-1.11.2
• Component/s: iPOJO
• Assignee: Clement Escoffier

Description

The iPOJO manipulator also manipulates inner classes within static methods. Then, if a method of such an instance is used, the following exception is thrown at runtime:

java.lang.IllegalStateException: java.lang.NoSuchFieldError: this$0

For me, it looks like that this issue is strongly related to FELIX-4347.

This code reproduces the error:

@Component
@Instantiate
public class ABC {

    @Validate
    public void start() {
        try {
            System.out.println(whereStringIs("foo").apply("bar"));
        } catch (Throwable e) {
            System.out.println("HUHU ");
            e.printStackTrace();
        }
    }

    private static Predicate<String> whereStringIs(final String blub) {
        return new Predicate<String>() {
            @Override
            public boolean apply(String input) {
                boolean result = input.equals(blub);
                return result;

            }
        };
    }

}

Exception:
