Description

I'm noticing a problem trying to build the Debian Flink Operator image from the Dockerfile in the main branch.

 

podman build -f Dockerfile -t debian-release:1.5.0-rc1

....

[INFO] Compiling 9 source files to /app/flink-kubernetes-operator-autoscaler/target/test-classes

[ERROR] COMPILATION ERROR :

I've tried increasing my nofiles to unlimited, but still see the error.

I tried building the release 1.4.0 and it built fine, so not certain what's recently changed in 1.5.0. Maybe it builds fine in Docker instead of podman?
