I guess that these are enough for the foreseeable future:
Max archive size: Long.MAX_VALUE
Max size of individual entry: Long.MAX_VALUE
Max number of file entries: Integer.MAX_VALUE
Java APIs don't suppport bigger files and I guess that so big files
won't be common even if file system sizes allowed them. If you write
ten terabytes per second, it will still take well over a week to
create an archive of 2^63-1 bytes.
I don't know how much memory one file entry needs, but let's assume
it takes only 50 bytes, including the overhead of the linked list
etc. Keeping a list of 2^31-1 files will then need 100 GiB of RAM.
While it might be OK in some situations, I hope such archives won't
become common. ;-) Even if the number of files is limited to
Integer.MAX_VALUE, it can be good to think about the memory usage
of the data structures used for the file entries.
