In October 2025, Chung worked on the apache/incubator-seata repository, focusing on stabilizing the build process by resolving a Spotless compatibility issue with Java 25. He addressed a critical bug that restored the mvn spotless:apply command in CI, ensuring reliable release pipelines and reducing build failures. His technical approach involved updating build tools and clarifying code comments in TransactionalTemplate.java to prevent ambiguity for future contributors. Chung also updated release notes in both English and Chinese and added a contributor acknowledgment. His work leveraged Java, Markdown, and release management skills, contributing to smoother onboarding and more predictable project maintenance.
