Release Note: `ObjectInputStream::readObject()` Should Handle Negative Array Sizes without Throwing `NegativeArraySizeExceptions`

`ObjectInputStream::readObject()` now throws a `StreamCorruptedException` instead of a `NegativeArraySizeException` when reading an array with a negative array size from a corrupted object input stream. Collection classes with a custom `readObject()` method which previously threw a `NegativeArraySizeException` when the number of their elements read from the deserialization stream was negative will now throw a `StreamCorruptedException` instead.
