From 2b997c1df6b91ab6866d9d66bd3ca3d82e7947d3 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Aur=C3=A9lien=20Mino?= Date: Mon, 14 Sep 2026 08:14:40 +0200 Subject: [PATCH 1/6] Resolve record component accessors in property access foo.bar never resolved to a record's generated bar() accessor, only to getBar()/isBar(), a public field, or duck-typed get(Object). Add a RecordGetExecutor that matches property to record component and lets Introspector resolve the actual accessor Method, so it still goes through the usual permission checks. Detection is done entirely via reflection (Class#isRecord(), Class#getRecordComponents()) since this module still targets Java 8; on such a runtime these methods simply don't exist and discovery quietly reports no match. The new test compiles its record fixtures on the fly with javax.tools.JavaCompiler and skips itself below Java 16, since 'record' isn't valid syntax at this module's source level either. --- .../introspection/RecordGetExecutor.java | 185 ++++++++++++++++++ .../internal/introspection/Uberspect.java | 4 + .../jexl3/RecordPropertyAccessTest.java | 102 ++++++++++ 3 files changed, 291 insertions(+) create mode 100644 src/main/java/org/apache/commons/jexl3/internal/introspection/RecordGetExecutor.java create mode 100644 src/test/java/org/apache/commons/jexl3/RecordPropertyAccessTest.java diff --git a/src/main/java/org/apache/commons/jexl3/internal/introspection/RecordGetExecutor.java b/src/main/java/org/apache/commons/jexl3/internal/introspection/RecordGetExecutor.java new file mode 100644 index 000000000..8dd84d285 --- /dev/null +++ b/src/main/java/org/apache/commons/jexl3/internal/introspection/RecordGetExecutor.java @@ -0,0 +1,185 @@ +/* + * Licensed to the Apache Software Foundation (ASF) under one or more + * contributor license agreements.

Fix RecordPropertyAccessTest's on-the-fly compiled record fixture to actually compile into org.apache.commons.jexl3 (it previously compiled with no package, then looked itself up under that package, which does not resolve). Also switch the test to extend JexlTestCase and use the shared restricted-permissions engine instead of a bespoke UNRESTRICTED-permissions one, matching the rest of the suite. Builds on the record accessor support originally proposed by Aurelien Mino in #415.
