Summary

Bundles Cpanel::JSON::XS (and ::Type / ::Boolean) for PerlOnJava by inheriting the same JSON::PP stack already used by bundled JSON, with small wrappers for CPAN-visible calling conventions.

Also fixes strict subs handling for fully qualified barewords such as Cpanel::JSON::XS::Type::JSON_TYPE_INT when the sub is only installed at runtime (typical use_ok then use constant ordering in smoke tests). Stock Perl 5 still rejects those at compile time; PerlOnJava now resolves them at runtime via QualifiedBarewordSubCall.

Tests

  • make (unit tests + shadowJar): PASS
  • JPERL_TEST_FILTER=Cpanel-JSON-XS ./gradlew testModule: PASS

Notes

  • encode_json strips a leading invocant only when it is a blessed instance of Cpanel::JSON::XS (Scalar::Util::blessed), so plain hash/array refs are never passed to isa.
  • Bundled smoke 00_smoke.t uses 9 planned tests (three use_ok plus six assertions).

…words

- Add Cpanel::JSON::XS inheriting bundled JSON::PP with encode_json/decode_json
  wrappers (class-method invocant strip via Scalar::Util::blessed; allow_nonref;
  croak on type-aware extras).
- Ship Cpanel::JSON::XS::Type (pure-Perl constants) and ::Boolean.
- Interpreter + JVM: under strict subs, treat Package::Name::sub barewords as a
  runtime nullary sub lookup (QualifiedBarewordSubCall) so use_ok + use constant
  ordering matches CPAN-style smoke tests.
- Document bundled module and xs-compatibility; changelog and feature matrix.

Remove QualifiedBarewordSubCall and the bytecode/JVM paths that treated
fully qualified barewords as late-bound nullary subs under strict subs.
Stock Perl 5 rejects those at compile time.

Bundled Cpanel::JSON::XS smoke resolves JSON_TYPE_INT via ->can after use_ok.

Add dev/modules/cpanel_json_xs.md and index it from dev/modules/README.md.

…ch layout

- Ship bundled CPAN distroprefs as YAML under PerlOnJava/CpanDistroprefs/
- Copy prefs/patches from jar via CPAN::Config bootstrap (remove inline heredocs)
- Add Net-Server and CPAN-FindDependencies patch files; un-ignore CpanPatches/**/*.patch
- Remove duplicate CPAN/Prefs/*.yml; add Prefs/README pointer
- Add dev/design/patch-and-cpan-prefs-layout.md; cross-link guides and roadmap
- Note import vs CPAN patch pipelines in sync.pl header

- Add dev/tools/test-cpan-distroprefs.sh and Makefile target (shadowJar + jcpan -t)
- Moose: PerlOnJava::Distroprefs::Moose::test_phase runs prove but reports OK to CPAN
- OpenAI::API smoke: 3600s timeout (cold CPAN home pulls many deps)
- Skip XML::LibXML by default (INCLUDE_XML_LIBXML_IN_DISTROPREF_SMOKE=1 to opt in)
- Document XML opt-in and SKIP_* knobs in design doc
