Hi everyone,

We have an Opencast 8.x installation which is now failing at startup on our dev system with the error below.

Any advice? No code or config changes recently which would explain this, and the same java version as on our production system, which is

# java -version

openjdk version "1.8.0_312"

OpenJDK Runtime Environment (build 1.8.0_312-8u312-b07-0ubuntu1~20.04-b07)

OpenJDK 64-Bit Server VM (build 25.312-b07, mixed mode)

Cheers

Stephen

Sorry, our mixup. Wrong java version used inadvertently. It was actually running java 11.

Cheers
