Línea de trabajo

The bug is in PerlOnJava's stash iteration, so start with the code that implements %{*{"::"}} and per-package stash hashes, checking whether named subroutine CODE slots are exposed. Reproduce with the four-line Perl script in the issue, expecting found=Bar1::bar. Done means that script prints the expected output and a focused regression test for enumerating a declared package sub passes on both JVM and interpreter backends.

Descripción

area:runtime bug

Root cause

Aspect 1.04 discovers statically matched subs in Aspect::Pointcut::match_all by iterating package stashes (each %{*{"::"}} and then each package stash) and checking defined *ENTRY{CODE}. PerlOnJava's stash iteration does not expose named subroutine entries through that traversal: with Bar1::bar declared, Aspect::Pointcut::Call->new('Bar1::bar')->match_all prints Bar1::bar on system Perl but an empty list on PerlOnJava. As a result, Aspect installs no advice wrapper for the target; before, after, and around advice never run. The same behavior occurs on both JVM and interpreter backends.

Reproducer

use strict;
use Aspect;
package Bar1;
sub bar { 'value' }
package main;
my $p = Aspect::Pointcut::Call->new('Bar1::bar');
print 'found=', join(',', $p->match_all), "\n";

Expected: found=Bar1::bar

Actual on PerlOnJava: found=

Evidence

  • Distribution: Aspect 1.04, CPAN run 20261008-181412-1954.
  • System Perl 5.42.2: full upstream suite passed, 28 files / 873 tests.
  • PerlOnJava 5.44.1, JVM and interpreter: full run failed 22/28 files, 168/671 subtests; focused t/31_feature_caller.t failed the nine expected advice-count assertions on both backends.
  • Root cause confirmed directly by comparing match_all output for the reproducer on system Perl and PerlOnJava.
  • Environment: macOS arm64, OpenJDK 24.0.2.

Fix package-stash iteration so named CODE entries are visible to Aspect's runtime stash traversal. Add focused regression coverage for enumerating a declared package sub through this traversal, then rerun the Aspect suite on both backends.
