封闭类:

InstantiationUtil

public static class InstantiationUtil.FailureTolerantObjectInputStream
extends InstantiationUtil.ClassLoaderObjectInputStream

An ObjectInputStream that ignores serialVersionUID mismatches when deserializing objects of anonymous classes or our Scala serializer classes and also replaces occurences of GenericData.Array (from Avro) by a dummy class so that the KryoSerializer can still be deserialized without Avro being on the classpath.

The TypeSerializerSerializationUtil.TypeSerializerSerializationProxy uses this specific object input stream to read serializers, so that mismatching serialVersionUIDs of anonymous classes / Scala serializers are ignored. This is a required workaround to maintain backwards compatibility for our pre-1.3 Scala serializers. See FLINK-6869 for details.
