Describe the bug

When combining certain libraries into a spring boot application and using the Spring provided ObjectMapper it fails to deserialize json to a class that has primitive integer fields.

Version Information

2.17.0

Reproduction

https://github.com/pstreef/jackson-primitive-int-issue

Expected behavior

The test readerForListOnRecordWithIntField in JacksonTest.java does not fail.

Additional context

It seems that there is a conflict caused by some kotlin module.

Kotlin-specific as per stack trace, will move to proper repo.

[k163377]

This seems to be a problem with kotlin-reflect.
https://youtrack.jetbrains.com/issue/KT-58649

Unfortunately, it is not a fixable issue in kotlin-module, so this issue is closed.

[k163377]

I jumped to conclusions a little too quickly.
I have made the fixes for 2.17.1, as it was possible to skip processing of classes defined in Java with a simple fix.
#779

[ohadgur]

hello @k163377 , thanks for this fix!
Sorry if I'm rude, but can I ask when is this fix will be released?

[k163377]

@ohadgur
I can only say that it is the next release.
2.17.1 or 2.18.0.
