After a refinement to the checks under development in #5709, the new checks 
examine array types of serial fields and warn if the underlying component type 
is not serializable. Per the JLS, all array types are serializable, but if the 
base component is not serializable, the serialization process can throw an 
exception.

>From "Java Object Serialization Specification: 2 - Object Output Classes":

"If the object is an array, writeObject is called recursively to write the 
ObjectStreamClass of the array. The handle for the array is assigned. It is 
followed by the length of the array. Each element of the array is then written 
to the stream, after which writeObject returns."

The jdk.jlink module has one instance of this coding pattern that needs 
suppression to compile successfully under the future warning.
