Thanks for driving this. Generally speaking, upgrading JDK is necessary to continue to iterate. However, considering the current situation of some companies and backward compatibility, can we deprecate JDK 8 in 0.9, but still support it(we can support this by running different versions of JDK at the same time) , and then consider deleting it from 1.0 or later versions (deprecation lasts for at least two versions, Flink deprecated JDK from 1.15, 1.20 - the current LTS version is still supported); In addition, considering the supported JDK versions, do we need to support JDK 11? From here[1], we can see that JDK 17 has a longer life cycle than JDK 11
