Suppress legacy PMD findings and enforce PreserveStackTrace/CloseResource/AssignmentInOperand rules #4453

shai-almog · 2026-01-20T14:40:08Z

Motivation

The codebase contains many existing PMD findings for PreserveStackTrace, CloseResource, and AssignmentInOperand that would break the quality gate if enforced as forbidden rules.
The intent is to allow fixing new violations going forward while avoiding a mass refactor of legacy code right now by silencing historical findings and making the rules fail the quality report for new occurrences.

Description

Added @SuppressWarnings(...) annotations to affected classes/interfaces across the codebase to silence existing PMD.PreserveStackTrace, PMD.CloseResource, and PMD.AssignmentInOperand findings (about 70 files updated, e.g. CodenameOne/src/com/codename1/capture/Capture.java, CodenameOne/src/com/codename1/io/ConnectionRequest.java, CodenameOne/src/com/codename1/io/gzip/CRC32.java).
Updated the quality gate script .github/scripts/generate-quality-report.py to treat PreserveStackTrace, CloseResource, and AssignmentInOperand as forbidden PMD rules so new violations will fail the report.
Suppressions were applied at the class level (using @SuppressWarnings({...})) to avoid changing language-level resource handling patterns (the codebase cannot uniformly adopt try-with-resources) while allowing future fixes to be introduced deliberately.

Testing

No automated tests were executed as part of this change. The change is limited to annotations and the quality-report rule set and requires CI to validate that newly added PMD violations now fail the quality report.
