Research direction

First, review the referenced comment at https://github.com/OpenAPITools/openapi generator/issues/3251#issuecomment 507103814 to understand why the dependency should be removed. Then, examine the pom.xml file in the repository root to locate the threetenbp dependency. Check the codebase for any imports or usage of threetenbp classes to determine if it is still needed. If it is unused, remove the dependency and update any related configurations. Ensure that the project compiles and tests pass after the change.
