Hutool 3.9 File

The 3.9 release structure is defined by the cn.hutool.core root package, segmented into:

| Area | Limitation | |------|-------------| | JDK support | JDK 11+ works but not optimized for modules. | | Performance | JSON parser slower than Jackson. | | Async HTTP | No built-in async client (added in 5.x). | | Tree structure | TreeUtil exists but less powerful than 5.x. | Hutool 3.9
