Monitor Service - java.io.NotSerializableException

Current Situation

• The Monitor Service is used for synchronization between the History and Notification services.
• If the services were stopped and not all entries have been synchronized, then the Monitor Service writes unsynchronized entries in a serialized (compressed) format to the database.
  • In this case a java.io.NotSerializableException error can occur, e.g.:

    java.io.NotSerializableException: com.sos.joc.monitoring.model.HistoryMonitoringModel
    at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1185) ~[?:?]
    at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1553) ~[?:?]
    at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1510) ~[?:?]
    at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java:1433) ~[?:?]
    at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1179) ~[?:?]
    at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:349) ~[?:?]
    at com.sos.commons.util.SOSSerializer.serializeCompressed2bytes(SOSSerializer.java:52)

Desired Behaviour

• Compressed serialization of unsynchronized entries should work
