Hi

I have this warning message but I don't find the place to trace it and, of course, how to fix that 👍

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by com.google.gson.internal.reflect.UnsafeReflectionAccessor (file:/home/fred/.m2/repository/com/google/code/gson/gson/2.8.6/gson-2.8.6.jar) to field java.time.LocalDate.year

I don'y know which information I can add.

    <java.version>1.8</java.version>
    <tomcat.version>9.0.37</tomcat.version>

Do not hesitate to ask me any information if my message isn't enough clear

Gson is a Java 6 oriented library. All standard runtime library classes to appear in Java 8 are not supported by Gson out of box. All "simple" data classes of java.time.* are among of those. You should create a custom type adapter to support java.time.LocalDate, and do the same for all the classes you need from that package. See also: #1059, #1807, and please don't forget to close the issue.
