Tsz-wo Sze commented on HDDS-10753:
-----------------------------------
bq. Shallow copy of list of immutable objects ({{{}OzoneAcl{}}}) should be fine.
If the shallow copy of the list is changed, the original list (say in cache)
will also be changed. Would it cause problems?
> OmKeyInfo#acls is not thread safe

> that OMKeyInfo#copyObject is just a shallow copy. It is not thread safe
> since OmKeyInfo#acls is just an ArrayList.
