Research direction
Read com/alibaba/fastjson2/JSONFactory.java and trace references to NAME_CACHE and NAME_CACHE2 before making changes. Run the existing Java tests to check for regressions; done means the two static caches no longer impose the reported resident-memory cost while the project remains passing.
