GitHub API and Open-AI crashes with Jackson update #1314
Description
GitHub-API
We have just updated our Jackson (#1313) and that leads to the bot crashing:
java.lang.NoSuchFieldError: Class com.fasterxml.jackson.databind.PropertyNamingStrategy does not have member field 'com.fasterxml.jackson.databind.PropertyNamingStrategy SNAKE_CASE'

at org.togetherjava.tjbot.Application.runBot(Application.java:91)
at org.togetherjava.tjbot.Application.main(Application.java:65)Reason is this foreign code:
static {
MAPPER.setVisibility(new VisibilityChecker.Std(NONE, NONE, NONE, NONE, ANY));
MAPPER.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
MAPPER.configure(MapperFeature.ACCEPT_CASE_INSENSITIVE_ENUMS, true);
MAPPER.setPropertyNamingStrategy(PropertyNamingStrategy.SNAKE_CASE);
}from GitHubClient coming from this dependency:
implementation 'org.kohsuke:github-api:1.329'So apparently this dependency is using our Jackson instead of its own, leading to the crash.
Until this is fixed, Jackson can not be updated anymore, our pipeline is blocked.
This also includes the GitHub-API itself whose newest version updates its Jackson and that bleeds into our dependency...
Open-AI
The same happens with Open-AI apparently:
Cant update Jackson.
Activity
Revert Jackson update, crashing (see #1314)

The Github-API just upgraded their Jackson, leading to the same crash since it bleeds into our project...
For the time being, I merged both, the upgrade for GitHub-API and our Jackson, so they both align again.
This really has to be addressed...

Is this issue fixed? or still open?
Zabuzard commentedon Sep 11, 2025
its still there. im not sure how much we can do on our side. ideally these ext frameworks would shade their dependencies or something

Someone already opened this issue on Github dependency that we're using
hub4j/github-api#2166
seems like they're fixing in two parts, out of which first one was merged last week
hub4j/github-api#2182
not sure how long till this is out
