Exception when running the dump-segment tool

Description

Hi,

I'm trying to run the 'dump-segment' tool, and getting the following exception -

# java --add-opens java.base/java.lang=ALL-UNNAMED -classpath "/opt/apache-druid-25.0.0/lib/*"  -Ddruid.extensions.loadList="[]" org.apache.druid.cli.Main tools dump-segment -d /tmp/segment/

My Java version is -

# java --version
openjdk 17.0.5 2022-10-18
OpenJDK Runtime Environment (build 17.0.5+8-Ubuntu-2ubuntu120.04)
OpenJDK 64-Bit Server VM (build 17.0.5+8-Ubuntu-2ubuntu120.04, mixed mode, sharing)

(even though I tried also Java 19 on Windows, and got the same exception...)

Am I missing something? Or maybe some change broke the dump-segment tool?

Thanks!

Tested with an older version now - 0.16.1 (from https://archive.apache.org/dist/incubator/druid/), and it works fine.
