The gap it fixes
These four thresholds are documented in HikariCP's own README and wiki, but nothing enforces them at config-write time — a typo or a copy-pasted value from an unrelated setting (seconds instead of milliseconds is a real, common mistake) silently produces a pool that either fails fast on every borrow or never actually rotates connections.
