Worked on the alibaba/fastjson2 repository to enhance the accuracy of JSONB parsing configuration documentation. Focused on aligning the documentation with actual Java code behavior by correcting the referenced JSONReader.Feature option, replacing SupportBeanArrayMapping with SupportArrayToBean. This targeted update addressed a potential source of misconfiguration, reducing user confusion and support needs. The work involved careful review of both documentation and code to ensure consistency, leveraging skills in Java and technical documentation. By clarifying configuration options, the update improved the developer experience and facilitated smoother adoption of JSONB parsing features without introducing new features or major code changes.
