Comments

SQE gives waiver on the 100% public API cc for integration of Vector API into jdk16 based on the agreement with Dev team to reach public 100% after integration and before RDP1 of jdk16.

Initiate the implementation reviews in parts with the community. The plan is to create multiple webrevs as follows: * Webrev for Vector API Java portion for review with core-libs * Webrev for Vector API functional tests for review with core-libs * Webrev for Vector API jmh performance tests for review with core-libs * Webrev for shared hotspot changes for review with hotspot-dev * Webrev for platform specific hotspot changes for review with hotspot-dev Patches for review are planned to be ready in March, some sooner than others.
