Jdk8Serializer.findReferenceSerializer() leads to StackOverflowError in 2.8.9

[gmokki]

The commit 4d71c27 made the Jdk8Serializer.findReferenceSerializer method to go into infinite recursion if the matched reference type is not found.

Before the commit the method returned null, I think the author intended to call super.findReferenceSerializer at the end like the code does in the findSerializer method.

Currently 2.8.9 release is unusable for code that registers Jdk8Module

Oh shoot. Yes, that's... not good. And yes, author may have planned to do super.findXxx() (which would be no-op). Too bad I didn't notice this on reviewing the patch.

Failing test could perhaps try serializing AtomicReference, the only reference type that jackson-databind provides.

Do you know if this might also be the case for 2.9.0.pr4?

@cowtowncoder Any chance to get this fix in a Jackson 2.8.x bugfix release?

[cowtowncoder]

@joschi It will be, once 2.8.10 is released:

https://github.com/FasterXML/jackson/wiki/Jackson-Release-2.8.10

but I'll have to figure out when to take time to cut this release, most likely the final full 2.8 release now that 2.9.0 is out.
