Does zeus only support jdk 11 +

[every-breaking-wave]

when I use a spark image built by myself with jdk8, I met following error: I found a reasonable answer In StackOverflow So if there's a way to make it compatible with jdk8?

It works with Java 8 only, maybe check once if your runtime version is correct and the binary+rss client jars were compiled with correct version?

Perhaps javac --release 8 works.
