April 2026 Monthly Summary for PicnicSupermarket/error-prone-support Focus: improve numeric signum comparisons across core numeric types and strengthen static analysis rules to increase code quality and maintainability. What was delivered: - Refactor of signum comparison idiom for BigDecimal, Integer, and Long using Refaster rules to prefer comparisons with 0 over 1 or -1, aligning with idiomatic Java usage. Commit: 0d0bb79307f24671d644b80cae4b6428cd3a8432. - Standardized signum checks across numeric types, improving readability and reducing the risk of incorrect boundary comparisons. - Updated error-prone rules to enforce the new idiom, boosting static analysis coverage and long-term maintainability. - Clear business value: reduces defect potential in numeric boundary checks, simplifies future changes, and improves onboarding through a consistent pattern across the codebase.

December 2025: Security hardening and reliability improvements for the MariaDB Docker configuration in the jhipster generator project. Implemented correct config directory usage and read-only enforcement for configuration files to reduce risk and align with container best practices.
