JDK-8310821 - Add tests for accidental changes to the serialized form of a class
Description
A new field 'putMode' had been added to LinkedHashMap in the initial Sequenced Collection implementation (JDK-8266571). Since the class is serializable, this resulted in an unintended change to the serial format. The field should be marked 'transient' to restore the previous serial format.
