+As the official Nexus Delta image moves to JRE 17, one dependency now requires the addition of
+`--add-opens=java.base/java.lang=ALL-UNNAMED` in `JAVA_OPTS`. This option is present by
+default in the image. However, if you are setting a custom value for `JAVA_OPTS` in your
+deployment, it is required to append `--add-opens=java.base/java.lang=ALL-UNNAMED` to it.
+This is because the custom value will override the one from the image.
