# Quick Task 001: Update JDK Requirement Summary
|
|
|
|
**JDK requirement updated to 21+ with Loom virtual threads rationale for JDBC blocking operations in Quill**
|
|
|
|
## Performance
|
|
|
|
- **Duration:** <1 min
|
|
- **Started:** 2026-02-05T12:07:20Z

|
|
- **Tasks:** 1
|
|
- **Files modified:** 1
|
|
|
|
## Accomplishments
|
|
- Updated JDK version requirement from 17+ to 21+ in Language & Runtime table
|
|
- Added rationale explaining Loom virtual threads benefit for JDBC blocking operations
|
|
- Clarified that ZIO fibers and JVM virtual threads are complementary, not competing
|
|
|
|
## Task Commits
|
|
|
|
Each task was committed atomically:
|
|
|
|
1. **Task 1: Update JDK requirement in research/STACK.md** - `64dcded` (docs)
|
|
|
|
## Files Created/Modified
|
|
- `.planning/research/STACK.md` - Updated JDK requirement and added Loom rationale note
|
|
|
|
## Decisions Made
|
|
- JDK 21+ is the new baseline (was 17+) - both are LTS releases
|
|
- Rationale focuses on JDBC blocking operations which benefit from Loom virtual threads
|
|
- Explicitly clarifies that ZIO's fiber system is complementary to JVM virtual threads
|
|
|
|
## Deviations from Plan
|
|
None - plan executed exactly as written.
|
|
|
|
## Issues Encountered
|
|
None
|
|
|
|
## User Setup Required
|
|
None - documentation-only change.
|
|
|
|
## Next Phase Readiness
|
|
- Stack documentation now accurately reflects JDK 21+ requirement
|
|
- Ready for Phase 2 planning
