调研方向

Start by reviewing the project’s Apache POI dependency declarations and build configuration, then identify usages of APIs removed in POI 6.x and tests that cover formula formatting and malformed files. Upgrade the dependency and adapt affected code and tests for the listed JDK, API, behavior, and parsing changes. Done means the project builds and its relevant tests pass with POI 6.x.

Motivation

Background

Upgrade Apache POI to 6.x to benefit from the latest features, performance improvements, and security fixes.
Reference: POI 6.0.0 Changes

⚠️ Key Breaking Changes

  1. JDK Requirement: Minimum version raised to JDK 17 (was JDK 8 in 5.x).
  2. API Removal: Methods marked as @Deprecated in 5.x have been completely removed.
  3. Behavior Change: DataFormatter now uses cached values for formula cells by default.
  4. Dependency Upgrades: Major upgrades to xmlsec, bouncycastle, commons-*, etc. (JPMS users require explicit module resolution).
  5. Stricter Parsing: Corrupted or malformed xlsx/docx files will be rejected outright, which may affect edge-case tests or legacy file handling.
