Josh England updated FLINK-35554:
---------------------------------
Description:
We use flink-docker to create a "standalone" application, with a Dockerfile
like...
{code:java}
FROM flink:1.18.1-java17
COPY application.jar /opt/flink/usrlib/artifacts/
{code}
However, after upgrading to 1.19.0 we found our application would not start. We
saw errors like the following in the logs:
{noformat}

class.

We were able to fix the issue by placing the application.jar in /opt/flink/lib
instead. My guess is that the usrlib directory isn't being added to the
classpath by the shell scripts that launch flink from a container.
