Is this comment just agreeing with the proposed behaviour stated here?
At the moment the code prohibits "read-only && create". It's an illegal
argument exception (see tests).
The only allowed access mode options with "create" are "readWrite" or
<no-option>, and in both cases you get back a ZipFileSystem for which
"isReadOnly()" is false. We'd already agreed that any explicit access mode
needs to always be honoured.
