Which has better activity and maintenance signals?

Based on the repository data provided, I can compare activity levels:

mybatis/mybatis-3:

• 20,435 stars, 12,874 forks
• Active CI/CD: GitHub Actions workflows configured for Java CI with coverage tracking (Coveralls) and code quality gates (SonarCloud)
• Recent test infrastructure: README notes testing configuration dated 12/28/2024 with 1,899-1,934 tests depending on platform
• Explicit test exclusion groups and platform-specific adjustments, indicating active maintenance

stleary/json-java:

• Repository data includes CodeQL analysis workflow and test utilities
• CONTRIBUTING.md references maintenance-phase status: "Because this project is currently in the maintenance phase, the kinds of changes that can be accepted are limited"
• Points users to FAQ for guidance on contribution scope

Verdict: mybatis/mybatis-3 shows stronger maintenance signals. It has significantly higher star/fork counts, more recent test infrastructure updates (dated 12/28/2024), active CI pipelines with code quality monitoring, and appears to be in active development. By contrast, stleary/json-java explicitly identifies itself as being in "maintenance phase" with limited scope for changes, suggesting lower development velocity.
