Re: [jackson-user] Jackson 2.13.0-rc2 released; more time for testing the Release Candidate, fix bugs

[Tatu Saloranta]

Excellent! Thank you for reporting these issues and working with us on
resolving them.

And PJ has done a really good job with the Scala module, as usual. Now it's
just me who has to get 2.13.0 out before September ends... :)

Re: [jackson-user] Jackson 2.13.0-rc2 released; more time for testing the Release Candidate, fix bugs

[Nakamura]

OK, I did some more research.  Two updates:

1.  Filed an issue
 about the
malformed class name
2.  I looked into the JsonNode thing.  Basically we were creating an empty
ArrayNode, and calling ArrayNode#add(Short).  Previously, this inserted an
IntNode, but now it inserts a ShortNode.  This seems like a bugfix, so I
don't think we need to take any action.

The scala bug is the only thing that I think would prevent us from
upgrading right now, but I'll try to confirm in the next couple of hours.

Interesting. I do not have a good idea here; although I do know that
the comparison across different node types and esp. for Numeric types
is challenging in general.
This is one reason why external comparator approach with JsonNode method:

public boolean equals(Comparator comparator, JsonNode other) {

is strongly recommended; plain `equals()` is notoriously difficult to
make work reliably (has to work "both ways" across different types
etc).

Having said that, IntNode.equals() and ShortNode.equals() appear
unchanged between 2.11 and 2.13; and both would fail comparison
(they assume strict type equality).
So the issue is probably more with construction of ShortNode vs
IntNode for some input...

That is a weird one for sure.

The location of `module-info.class` did move from main-level (in 2.11
and 2.12) to under `META-INF/versions/11`: this to prevent issues with
some older Java 8
clients. But no idea how this could cause other issues.

Re: [jackson-user] Jackson 2.13.0-rc2 released; more time for testing the Release Candidate, fix bugs

[Nakamura]

OK, I haven't finished working through the issues yet.  I'm trying to
upgrade from 2.11.4 to 2.13.0-rc2.  After fixing some expected breaking
changes, here are a few I found:

1. We have tests that compare the values of JsonNodes.  After the upgrade,
it started failing when it said that IntNode and ShortNode are not equal.
I haven't pinpointed what has changed (whether it's equality, or how things
are turned into ShortNode or IntNode). I'll update the thread once I've
figured it out.

2.  We have a test that tries to read all of the resources files.  When it
comes across jackson, it says "File Not Found".

Hi Tatu,
I've started testing with RC2 across my company's monorepo, and I'm seeing
a bunch of test failures.  Could you please wait until at least next week
to promote to stable?  I'll need some time to figure out which are fragile
tests vs real regressions.
Best,
Moses
