What java version are you using in the server?

From right there, in the log: java version 1.8.0_275

I asked what java are you using not java version

My mistake.
Running [java -version] on my system console (linux) shows:
openjdk version "1.8.0_275"
OpenJDK Runtime Environment (build 1.8.0_275-8u275-b01-1~deb9u1-b01)
OpenJDK 64-Bit Server VM (build 25.275-b01, mixed mode)

Is that the info you're asking about? If not then I'm really not sure what you mean.
