App is updated to avoid "illegal reflective access operation" warning

[izgeri]

Summary

When you run the app, it gives you a warning that it's doing something that should not be allowed and will not be supported in the future.

Steps to Reproduce

Run the app against a remote postgres DB instance:

docker run \
  -e DB_URL="postgresql://[DB_URL]:[DB_PORT]/{DB_DATABASE]" \
  -e DB_USERNAME="[DB_USER]" \
  -e DB_PASSWORD="[DB_PASS]" \
  -e DB_PLATFORM="postgres" \
  -p 8080:8080 \
  -d cyberark/demo-app
