Review Comment:
Hi, we can still use arrow and some internals, we are using it in production
but we are maintaining a fork to be able to load the classes. Otherwise, the
class simply does not load, and by consequence our classes are not loaded
neither. My main problem is we cannot control the JVM and set the
`--add-opens`, as our application is a plugin which is installed in clusters,
where we cannot control jvm initialization, sometimes in the cloud, which is
even more difficult to set `--add-opens`
