Java Profiling Workflow / Step 3 / Refactor code to fix issues

Implement refactoring based on profiling analysis: review profiling-problem-analysis-YYYYMMDD.md and profiling-solutions-YYYYMMDD.md, identify specific performance bottlenecks, and refactor code to fix them. Ensure all tests pass after changes.

What is covered in this Skill?

• Review analysis notes: docs/profiling-problem-analysis-YYYYMMDD.md, docs/profiling-solutions-YYYYMMDD.md
• Identify specific bottlenecks from the documented findings
• Refactor code to address CPU hotspots, memory leaks, threading issues, or other performance problems
• Run verification: ./mvnw clean verify or mvn clean verify

Scope: Changes must pass all tests. Apply fixes incrementally and verify after each significant change.

Constraints

Verify that changes pass all tests before considering the refactoring complete.

• MANDATORY: Run ./mvnw clean verify or mvn clean verify after applying refactoring
• SAFETY: If tests fail, fix issues before proceeding
• BEFORE APPLYING: Read the analysis and solutions documents for specific recommendations

When to use this skill

• Refactor performance
• Optimize hot path
• Performance refactoring
