During deserialization the following exception occurs:

                    classdata
                      com.mypackage.MyClass
                        values
                          myEnumField
                            (object)

Occasionally got the same.

The cause of this issue is enum field type of the object. I have created a pull request to fix this https://github.com/NickstaDB/SerializationDumper/pull/8

@NickstaDB could you please take a look and merge my pull request if the fix is correct?
