Hi @sigmaaa While you’re'in here, please also clean up remaining Java version references in one pass.

I still see older Java mentions in docs/en/faqs.rst and docs/zh_CN/faqs.rst. README_CN.md still has a Java 17 reference.

Please raise all compiler compliance to 21 as well (source / compliance / targetPlatform are still 17) and any other places.

I still see older Java mentions in docs/en/faqs.rst and docs/zh_CN/faqs.rst. README_CN.md still has a Java 17 reference.
Please raise all compiler compliance to 21 as well (source / compliance / targetPlatform are still 17) and any other places.

Hi @sigmaaa While you’re'in here, please also clean up remaining Java version references in one pass.
I still see older Java mentions in docs/en/faqs.rst and docs/zh_CN/faqs.rst. README_CN.md still has a Java 17 reference.
Please raise all compiler compliance to 21 as well (source / compliance / targetPlatform are still 17) and any other places.
