Fix for regression triggered by #2325 -- apparently, the API visitor would force all the lazy stubs so the `AbstractLazy` `writeReplace` was not exercised. With the private subtrees being ignored, the visitor didn't force the lazy stub, and the `writeProtected` method was not inherited in `SafeLazy.Impl`. From https://docs.oracle.com/javase/7/docs/api/java/io/Serializable.html `writeReplace` must be protected for its override to be inherited. > `Serializable` classes that need to designate an alternative object to be used > when writing an object to the stream should implement this special method with > the exact signature: > `ANY-ACCESS-MODIFIER Object writeReplace() throws ObjectStreamException;` > > This `writeReplace` method is invoked by serialization if the method exists and > it would be accessible from a method defined within the class of the object > being serialized. Thus, the method can have `private`, `protected` and > `package-private` access. > > **Subclass access to this method follows java accessibility rules.** (Thanks to retronym for digging up the docs.) The fix is captured, indirectly, by the scripted test `source-dependencies/java-analysis-serialization-error`. |
