Java 8 - how to access object and method encapsulated as lambda

It is possible, because the captured references are translated into fields of the runnable (as with all anonymous classes). The names will be not be consistent however.

I found by testing that you need to make myText non-final, otherwise it will be seen as a compile time constant and in-lined (and will not be accessible as a field):

private static void inspect(Runnable runnable) throws Exception {       
    for(Field f : runnable.getClass().getDeclaredFields()) {
        f.setAccessible(true);
        System.out.println("name: " + f.getName());
        Object o = f.get(runnable);
        System.out.println("value: " + o);
        System.out.println("class: " + o.getClass());
        System.out.println();
    }
}

Prints:

name: arg$1
value: test.SomePrintingClass@1fb3ebeb
class: class test.SomePrintingClass

name: arg$2
value: How to access this?
class: class java.lang.String
