SONARJAVA-6492: Implement S8912 - CredentialsProvider implementations should be annotated with @Unremovable by romainbrenguier · Pull Request #5707 · SonarSource/sonar-java

romainbrenguier · 2026-06-26T14:54:07Z

Summary

Implements rule S8912: Custom CredentialsProvider implementations in Quarkus should be annotated with @Unremovable when they have a CDI scope annotation, to prevent them from being removed by Quarkus's bean pruning mechanism.
Rule raises an issue on CDI-scoped classes implementing io.quarkus.credentials.CredentialsProvider that are missing the @io.quarkus.arc.Unremovable annotation.
Test sample uses mock stub types for io.quarkus.arc.Unremovable and io.quarkus.credentials.CredentialsProvider (no external library dependency added to pom.xml), following the same pattern as S8911.

Rspec PR: https://github.com/SonarSource/rspec/pull/7153

Test plan

Rule implementation correctly detects missing @Unremovable on CDI-scoped CredentialsProvider implementations
Compliant cases (with @Unremovable, or without CDI scope) are not flagged
withoutSemantic() test verifies no issues raised without semantic analysis
JavaAgenticWayProfileTest passes
CI ruling and autoscan tests pass (to be updated after CI run)

SONARJAVA-6492

- Added diff_S8912.json and updated autoscan-diff-by-rules.json with the new rule S8912 (FN=8) and corrected FN counts for S1128 (30→31), S1168 (24→25), and S6813 (66→67) - Fixed Sonar_way_profile.json by sorting rule keys numerically (by integer value) instead of lexicographically, as required by MetadataTest.ensure_sane_Sonar_way_profile - Sorted ruleKeys in Sonar_way_profile.json by numeric value instead of lexicographic order to fix MetadataTest.ensure_sane_Sonar_way_profile

Code Review ✅ Approved 2 resolved / 2 findings

Implements rule S8912 to enforce the use of @Unremovable on CDI-scoped CredentialsProvider implementations, ensuring consistency with Quarkus bean pruning requirements. Resolved formatting issues in the rule documentation and cleaned up unrelated rule additions in the profile configuration.

✅ 2 resolved

✅ Quality: S8912.html is raw AsciiDoc wrapped in a single

tag

📄 sonar-java-plugin/src/main/resources/org/sonar/l10n/java/rules/java/S8912.html:1-15
The new rule description S8912.html is written as raw AsciiDoc markup (=== Documentation, == Why is this an issue?, * bullet lists, bare URLs) enclosed inside one single <p>...</p> element. Every other rule description in this directory (e.g. the sibling rule S8911.html) is authored as proper HTML using <h2>, <h3>, <p>, <ul>/<li>, <a href>, <code>, etc.

Because the file is served verbatim to SonarQube/IDE clients (the GeneratedCheckListTest only checks that the file exists, not its structure), this rule's documentation will render as one unbroken paragraph: the ===/== headings, the * bullets and the raw URLs will all be displayed as literal text instead of headings, lists and links. The section ordering is also inverted relative to convention — === What is the potential impact? appears before == Why is this an issue?, and there is no How to fix it section.

Fix: convert the content to real HTML matching the S8911 structure — <h2>Why is this an issue?</h2>, <h2>How to fix it</h2>, <h2>Resources</h2>/<h3>Documentation</h3>, with <ul><li> lists and <a href="..."> links — and order the sections consistently with the other rules.

✅ Quality: Profile commit re-sorts file and adds two unrelated rules

📄 sonar-java-plugin/src/main/resources/org/sonar/l10n/java/rules/java/Sonar_way_profile.json:4-18 📄 sonar-java-plugin/src/main/resources/org/sonar/l10n/java/rules/java/Sonar_way_profile.json:534-541
The diff_stats/delta only surfaced +S2206 and +S2654, but the actual commit (5aefe2c) does much more to Sonar_way_profile.json:

Unrelated rule activations: Besides the intended S8912, this commit also activates S2206 and S2654 in the default Sonar way profile. Those rules were implemented in separate, already-merged PRs (SONARJAVA-6527 Implement rule S2206: Either fields or getters should be annotated for persistence but not both #5706 and SONARJAVA-6526 Implement rule S2654: JEE applications should not use threads or synchronization #5702) that did not add them to the profile. Activating two unrelated rules inside an S8912 PR is scope creep — it silently changes analysis results for every user on the default profile and should be a deliberate, separately reviewed change.

Whole-file re-ordering: The commit re-orders a large block of entries, moving S107, S108, S110, S112, S114, S115, S116, S117, S119, S120, S125, S127, S128, S131, S135 and S899 from their original (numeric) positions to new (lexicographic) positions — e.g. S899 jumps to the very end after S8924. The repo's existing convention orders entries numerically (S106, S107, ... S135, S899, S1065); this commit switches the moved entries to lexicographic string ordering, inconsistent with the rest of the file and producing a noisy ~35-line diff that obscures the real change.

This strongly suggests the profile was regenerated with a tool that uses a different sort order than the repo convention. Suggested fix: regenerate the profile using the project's standard generator so ordering matches convention, and limit this PR to adding only S8912. If S2206/S2654 genuinely belong in Sonar way, add them in their own commit/PR with explicit justification.

Maybe we should also add the javax equivalent here?

Since version 3.0, Quarkus is based on Jakarta EE 10 and I think it is mandatory to use the jakarta.* packages, so I don't know if it is necessary to add the javax variant

You're correct that Quarkus 3.0+ is based on Jakarta EE 10 and requires jakarta.* packages. However, I included the javax variants following the pattern used in other rules in this codebase (e.g., JEEThreadCheck at java-checks/src/main/java/org/sonar/java/checks/JEEThreadCheck.java:48-52, which supports both javax and jakarta variants for EJB annotations).

The rationale is that SonarJava analyzes existing codebases, some of which may still be using Quarkus 2.x with javax packages. Supporting both variants ensures the rule works across different Quarkus versions, which is helpful for users in the process of migrating from Quarkus 2 to 3.

That said, if the team's policy is to only support current framework versions (Quarkus 3.x+), I can remove the javax variants. What's your preference?

Good point. While Quarkus 3.0+ requires Jakarta EE 10, following the codebase convention seen in other rules (e.g., AtLeastOneConstructorCheck, ServletInstanceFieldCheck, Spring checks), I've added the javax equivalents to support potential legacy code or older Quarkus versions:

"javax.enterprise.context.ApplicationScoped", "javax.enterprise.context.RequestScoped", "javax.enterprise.context.SessionScoped", "javax.enterprise.context.Dependent", "javax.inject.Singleton"

Sorry about the verbose replies, that comes from the vibe-bot 😅

I thought we were not supposed to do security rules, did you ask code security about this rule? We could just keep the "reliability" impact, as it is probably the most important for this rule.

It's clearly a rule more about reliability than security, I'll remove the "SECURITY" entry from the rspec.

I did the update on the rspec side. It will be taken into account by the next "update metadata" run

The rule is probably a good candidate for a quickfix, we can put it as "targeted" so that it will be easier to find it if we want to implement quickfixes later
