Sorry Guys,
I'm testing an Akka-Cluster with two actor that send one to an another a
custom message formed by two Strings and an ActorRef.
When the second actor receives the message (serialized with kryo) it just
become unreachable.
That's the trace of the second actor:
00:35 TRACE: [kryo] Register class ID 0: int
(com.esotericsoftware.kryo.serializers.DefaultSerializers$IntSerializer)
00:35 TRACE: [kryo] Register class ID 1: String
(com.esotericsoftware.kryo.serializers.DefaultSerializers$StringSerializer)
00:35 TRACE: [kryo] Register class ID 2: float
(com.esotericsoftware.kryo.serializers.DefaultSerializers$FloatSerializer)
00:35 TRACE: [kryo] Register class ID 3: boolean
(com.esotericsoftware.kryo.serializers.DefaultSerializers$BooleanSerializer)
00:35 TRACE: [kryo] Register class ID 4: byte
(com.esotericsoftware.kryo.serializers.DefaultSerializers$ByteSerializer)
00:35 TRACE: [kryo] Register class ID 5: char
(com.esotericsoftware.kryo.serializers.DefaultSerializers$CharSerializer)
00:35 TRACE: [kryo] Register class ID 6: short
(com.esotericsoftware.kryo.serializers.DefaultSerializers$ShortSerializer)
00:35 TRACE: [kryo] Register class ID 7: long
(com.esotericsoftware.kryo.serializers.DefaultSerializers$LongSerializer)
00:35 TRACE: [kryo] Register class ID 8: double
(com.esotericsoftware.kryo.serializers.DefaultSerializers$DoubleSerializer)
00:35 TRACE: [kryo] Register class ID 9: void
(com.esotericsoftware.kryo.serializers.DefaultSerializers$VoidSerializer)
00:35 TRACE: [kryo] Register class ID 10: scala.Enumeration$Val
(com.romix.scala.serialization.kryo.EnumerationSerializer)
00:35 TRACE: [kryo] Register class ID 11: scala.Enumeration$Value
(com.romix.scala.serialization.kryo.EnumerationSerializer)
00:35 TRACE: [kryo] Registration required: false
00:35 TRACE: [kryo] Optimize ints: true
00:35 TRACE: [kryo] Field email: class java.lang.String
00:35 TRACE: [kryo] Field customerCode: class java.lang.String
00:35 TRACE: [kryo] Field sender: class akka.actor.ActorRef
00:35 TRACE: [kryo] Register class ID 20: com.test.common.LoginRequest
(com.esotericsoftware.kryo.serializers.FieldSerializer)
00:35 TRACE: [kryo] References: false
Thanks for any help,
Antonio
