Review Comment:
Fixed in c1aa008be631090a1f676470aa474fb6489ff319: `softEvictConnections()`
lives on `HikariPoolMXBean`, not on `HikariDataSource` directly. The fix
retrieves the MXBean via `getHikariPoolMXBean()` (a public method on
`HikariDataSource`) using reflection, then calls `softEvictConnections()` on
the MXBean. Tests updated accordingly to simulate the real two-step indirection.
