@vzorge Thanks for your contribution!

This is essentially the same PR as #165 right now.

Please also sync the actual Java code with com.fasterxml.jackson.datatype:jackson-datatype-jsr310:2.18.0.

The problem with #165 is that the build fails because the junit dependency update is not there.

@joschi What do you mean with syncing the Java code?

What do you mean with syncing the Java code?

This project is mirroring the code of com.fasterxml.jackson.datatype:jackson-datatype-jsr310 and replaces any use of java.time.* with org.threeten.bp.* to get a high degree of compatibility with the actual Jackson module plus making it compatible with older Java versions.

If you look at the changes of the upstream module at FasterXML/jackson-modules-java8@jackson-modules-java8-2.15.2...jackson-modules-java8-2.18.0, you can see that there were some changes since version 2.15.2 was released.

These changes have to be ported into this project.

@vzorge Any news? Do you have time to port the code changes?
