> The current implementation of RAMDirectory throws a NotSerializableException when trying to serialize, due to the inner class KeySet of HashMap not being serializable (god knows why)
> java.io.NotSerializableException: java.util.HashMap$KeySet
>         at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1081)
> Caused by line 43:
> private Set fileNames = fileMap.keySet();
> EDIT:
> while we're at it: same goes for inner class Values 
> java.io.NotSerializableException: java.util.HashMap$Values
>         at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1081)
> Collection files = fileMap.values();
