Hi Wolfgang,

I guess you are using the local file system store, and the problem only occurs 
if the last snapshot file is empty?

That does indeed sound like a real issue. Would you mind opening a ticket and 
add this information (with a longer more complete stack trace).

Hi

We using Akka 2.3.2 with akka-persistence in our project.
So far our experience with this new module are quite good :)
.
But recently we run into some troubles when using snapshots. In the case we 
shutdown our application we write some data
to some snapshots. Some how it happens sometimes that snapshot files are 
created but empty.

In the case of a restart of our application this empty snapshots causes this 
error.
If more revision of this snapshot are available and the last one does contain 
data, the error does not occur.

java.io.EOFException: null
        at java.io.ObjectInputStream$PeekInputStream.readFully(Unknown Source) 
~[na:1.7.0_25]
        at java.io.ObjectInputStream$BlockDataInputStream.readShort(Unknown 
Source) ~[na:1.7.0_25]
        at java.io.ObjectInputStream.readStreamHeader(Unknown Source) 
~[na:1.7.0_25]
        at java.io.ObjectInputStream.<init>(Unknown Source) ~[na:1.7.0_25]
        at 
akka.util.ClassLoaderObjectInputStream.<init>(ClassLoaderObjectInputStream.scala:16)
 ~[akka-actor_2.10-2.3.2.jar:na]

I would expect that an empty file should not cause an exception.

Regards

Wolfgang
