Dong Lin updated FLINK-30501:
-----------------------------
Description:
Flink 1.15 and later versions require at least Java 11 to build from sources
[1], whereas the pom.xml specifies the source/target is 1.8. This inconsistency
confuses users.
As mentioned in the FLINK-25247 title, the goal of that ticket is to "Inform
users about deprecation". It will be better to inform users that "Java 8 is
deprecated" instead of saying "Fink requires at least Java 11 to build", so
that users have the right information to make the right choice for themselves.
Also note that Flink community is regularly running flink-ml benchmark for both
Java 8 and Java 11 [2], which suggests that we are practically ensuring Java 8
is supported.
