Hoss Man updated LUCENE-785:
----------------------------
Attachment: ramdir.serializable.diff
maybe i'm missing something, but this seema like a trivail fix ... HashMap is
serializable -- it's just the persistent refrences to the keySet() and values()
Collections that arne't serializable (fileNames and files)
One is private, the other is package protected, so why don't we just get ride
of them and fetch as needed? (files isn't even used except in a Mock subclass
for testing purposes)
> RAMDirectory not Serializable

> Reporter: Matthias Seidel
> Assigned To: Michael McCandless
> Priority: Minor
> Attachments: ramdir.serializable.diff

>
> 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();
