I followed the installation docs, but encountered the following error when start server.

I used Ubuntu 22.04.1 LTS, openjdk version "1.8.0\_342", and stardog-8.2.1 version.  
I dont know how to solve this problem.

I've been stuck with this problem for days. I tried java8, java11, and some older versions of stardog (6, 7), but all got the above error.  
I think it's strange, but I don't know what can I do, can someone help me? Thanks.
