Hi all, Thanks for the feedback.
I have opened a PR to move this forward: https://github.com/apache/iotdb/pull/17859 The PR raises the minimum Java version to 17, updates the related build/runtime checks, upgrades dependencies that were previously constrained by the Java baseline, and migrates the REST/OpenAPI generated surface and related annotation usages from javax to jakarta where applicable. Please take a look and share your feedback.
