JDK 9+ Jackson Illegal Reflective access by ClassUtil still present in 2.10.1

[Mileta Cekovic]

Hi, seems JDK 9+ Illegal Reflective access by ClassUtil is still present in Jackson 2.10.1

Namely I got this with JDK 11.0.5, Jackson 2.10.1 then trying to serialize LocalDate to JSON using jackson-datatype-jsr310

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by com.fasterxml.jackson.databind.util.ClassUtil (file:/C:/Users/mcekovic/.gradle/caches/modules-2/files-2.1/com.fasterxml.jackson.core/jackson-databind/2.10.1/18eee15ffc662d27538d5b6ee84e4c92c0a9d03e/jackson-databind-2.10.1.jar) to field java.time.LocalDate.year

The problem here is that this gives no clue as to where and how access
was triggered.
If code path leading to it was known I could see if this could be
avoided -- I am quite confident that in case of this class,
introspection is not needed since there is explicit serializer -- but
without something like stack trace, it is not possible to really trace
back unfortunately.

So if anyone has good ideas on how to tease out some more information,
I would be happy to have a look at if and how to avoid triggering this
warning.

Looks like there are some command-line switches:

https://stackoverflow.com/questions/49076972/how-can-i-throw-an-exception-for-an-illegal-reflective-access-warning

where:

"--illegal-access=deny will cause the expected IllegalAccessException
or InaccessibleObjectException to be thrown. If you just want the
stack traces then --illegal-access=debug is what you are looking for.
"

would seem helpful in particular...

Unfortunately, I am unable to see absolutely any problem on Eclipse,
running with setting, unit test for `LocalDate`, for JSR-310 module.

So until it can be reproduced, there is nothing I can do.

Sorry for late reply, here is the stacktrace (with Jackson 2.10.2):

Spring Boot 2.2.2

Jackson 2.10.2

JDK 11.0.5, Windows 10 64b

jackson-datatype-jsr310 is in the class path
