RAMDirectory not Serializable
-----------------------------

                 Key: LUCENE-785
                 URL: https://issues.apache.org/jira/browse/LUCENE-785
             Project: Lucene - Java
          Issue Type: Bug
          Components: Store
    Affects Versions: 2.1
            Reporter: Matthias Seidel
            Priority: Minor


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();
