Review comment:
I can only think of a couple ways the cache could contain handles to
nonexistent files:
- If the file was deleted somehow.
- If the cache was serialized and shipped to workers. But we don't include a
JavaUdfLoader instance as part of CalcFn, instead we construct a new
JavaUdfLoader instance in `CalcFn::setup`. Besides, the cache is a static
variable, and static variables are never serialized.
