Other info you consider could help to fix it:

I've tried: (setq jdee-jdk-doc-url "https://docs.oracle.com/javase/8/docs/api/")
Also, I've looked for the exact error message on my several search engines, with no luck...

I had the same (or similar) problem. It was resolved by setting jdee-jdk-registry:

(setq jdee-jdk-registry '(("1.8" . "/usr/lib/jvm/zulu-8-amd64") ("1.11" . "/usr/lib/jvm/zulu11")))

You may also need to set jdee-jdk to ("1.11")
