Hi,
we are currently using akka 2.3.6 and checking for migration from scala
2.10.4 to 2.11.2. When I tried an update to scala 2.11.2, I noticed
following things:
When I start my application (using a local leveldb) I cannot reload
Snapshots - I get the following exception:
08:12:08.232 ERROR [akka.tcp://xxxxx@127.0.0.1:3552/system/snapshot-store]
Error loading snapshot [SnapshotMetadata(xxxx,3,1411970788025)]
java.io.InvalidClassException: scala.Option; local class incompatible:
stream classdesc serialVersionUID = -2062608324514658839, local class
serialVersionUID =
-114498752079829388
I have a similar issue with the akka-persistence-mongo-casbah journal:
07:43:03.534 ERROR [akka.tcp://xxxxx@127.0.0.1:3552/system/snapshot-store]
error loading snapshot { "_id" : { "$oid" : "5428f1275fe8f19e6086ec8c"}
, "persistenceId" : "xxxxxx" , "sequenceNr" : 0 , "timestamp" :
1411969319306 , "snapshot" : <Binary Data>}
java.io.InvalidClassException: akka.persistence.SelectedSnapshot; local
class incompatible: stream classdesc serialVersionUID =
-7413351535605152403, local clas
s serialVersionUID = -8204699298693905400
at java.io.ObjectStreamClass.initNonProxy(Unknown Source)
~[na:1.7.0_45]
I guess the only workaround for this would be touching the serializers?
Regards,
Christian
