perl-JSON-Any-1.40-7.fc45 fails to build in Fedora 45 because a test fails:

$ perl -Ilib t/04-ENV.t
ok 1 - got the right handlerType
ok 2 - got a JSON::Any object
not ok 3 - trapped a failure because of a non-reference
#   Failed test 'trapped a failure because of a non-reference'
#   at t/04-ENV.t line 28.
#                   undef
#     doesn't match '(?^:use allow_nonref)'
ok 4 - got another JSON::Any object
ok 5 - got the same data back again
ok 6 - no failure with config change
ok 7 - got another JSON::Any object
ok 8 - trapped a failure because the constructor option overrides the environment variable
1..8
# Looks like you failed 1 test of 8.

This failure is triggered by upgrading perl-Cpanel-JSON-XS from 4.41-1.fc45 to 4.42-1.fc45. This seems to be an intentional change, from CPAN-JSON-XS changelog:

> Change allow_nonref default to true (GH #241, matching JSON::PP and JSON::XS 4.0+ and the insecure RFC 7159). encode and decode now accept non-reference values by default. decode_json() with an explicit 0/1 second argument still works. allow_nonref(0) to disable scalars-only for secure JSON.
