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();
