Archive::Zip::Member is missing desiredCompressionMethod

Inspecciona la implementación incluida de Archive::Zip de PerlOnJava, donde se registra compressionMethod para los objetos miembro, y compárala con la API desiredCompressionMethod esperada descrita en el issue. Añade una prueba de regresión propia del proyecto para la selección de compresión de miembros y ejecuta IO-StructuredOutput-1.008 t/1.t tanto en el backend JVM como en el backend del intérprete para verificar que pasan las 37 pruebas.

Summary

IO-StructuredOutput-1.008 fails its complete upstream test suite on PerlOnJava because the bundled Archive::Zip::Member implementation does not provide the CPAN-compatible desiredCompressionMethod method.

CPAN evidence

• Distribution: IO-StructuredOutput-1.008
• Failing test: t/1.t
• Archived CPAN tester run: 20260915-125610-17469
• System Perl: PASS, 37/37 tests
• PerlOnJava JVM backend: FAIL, 16/37 tests; exit status 255
• PerlOnJava interpreter backend: FAIL, 16/37 tests; exit status 255

The system-Perl comparison was run in an isolated local library containing the target distribution and its missing pure-Perl dependencies. The full upstream test suite completed successfully there.

Failure

The test reaches the CSV-output case and then aborts when IO::StructuredOutput::output calls:

$member->desiredCompressionMethod(COMPRESSION_DEFLATED);

PerlOnJava reports:

Can't locate object method "desiredCompressionMethod" via package "Archive::Zip::Member"

The failure occurs in both execution backends and is reproducible with the dependency PERL5LIB overlay selected by the CPAN tester.

Expected behavior

Archive::Zip::Member should expose the compression-selection API expected by CPAN Archive::Zip, including desiredCompressionMethod, so the CSV output path completes and t/1.t passes all 37 tests.

Implementation evidence

The bundled PerlOnJava Archive::Zip implementation registers compressionMethod for member objects but does not register or implement desiredCompressionMethod. The Java-backed ZIP writer already supports stored and deflated compression methods, so this appears to be an API compatibility omission rather than an upstream or environment failure.

Environment

• PerlOnJava commit: 1ac22252c2ed069829f8769b9ceeb14372cd163f
• macOS Darwin arm64
• OpenJDK 24.0.2
• PerlOnJava reports Perl version 5.044001

Acceptance criteria

• Add desiredCompressionMethod compatibility for Archive::Zip::Member.
• Add a project-owned regression test covering member compression selection through the PerlOnJava implementation.
• Verify IO-StructuredOutput-1.008 t/1.t passes on both JVM and interpreter backends.
