I want to upgrade jdk for my webapp. But cassandra versions are of 3.0.15. Is there a way to make cassandra 3.0.15 work with JDK 11?

CodePudding user response：

Java 11 is only supported in Apache Cassandra 4.0 (see NEWS.txt).

Only Java 8 is supported for earlier versions of Cassandra. You will not be able to start Cassandra otherwise. Cheers!
