> The following class with not serializable object used through writeReplace will not be caught correctly by the SerializationDebugger
> {code}
> class SerializableClassWithWriteReplace()
>   extends Serializable {
>   private def writeReplace(): Object = {
>     new NotSerializableObjectI()
>   }
> }
> {code}
> The reason is that SerializationDebugger does not check the type of the replaced object (whether serializable or not).
