Just as a small project, I've been trying to make a wee thing that reads serialized lambdas (locally or from an FTP) and invokes their run functions as part of a test to experiment with file associations in Windows (i.e. opening certain file types opens them with a certain program) and whatnot, but no matter what I try, it never seems to properly deserialize.

The lambda was declared like so

```
Runnable r = (Runnable & Serializable) () -> {
    // blah blah
    // made sure not to capture anything
};

```

and serialized using a FileOutputStream wrapped by a[n optional] BufferedOutputStream wrapped by an ObjectOutputStream without issue. However, when deserialized [in a different project], it fails, saying that it could not find the enclosing class that contained the code for serializing it. I've tried various things like wrapping them in a serializable class (w/serialVersionUID = 0L for testing purposes) or defining a an interface that extends Runnable and Serializable, but to no avail.

Yes, I am aware that serializing lambdas isn't really good practice (or so we're told), but I'm not sure how to go about turning functions and subroutines into something I can store as a file or in an FTP. If this isn't even the right way at all, do tell.

Oh, I'm using Eclipse Luna of whatever the latest version is.

**Edit:**

Deserialized like so

```
File f = new File(somePath);
FileInputStream fish = new FileInputStream(f);
BufferedInputStream bos = new BufferedInputStream(fish); // not really necessary
ObjectInputStream ois = new ObjectInputStream(bos);
Runnable r = (Runnable) ois.readObject();
ois.close();
r.run();

```
