PROFILE
David Thompson
David Thompson contributed to the eclipse-jdt/eclipse.jdt.core repository by developing extensible code completion features, modernizing test suites, and enhancing Java version support. He implemented a plugin-driven CompletionEngine extension point and enforced stricter validation for RequiredDirective configuration, using Java and Eclipse plugin development skills. David also improved code maintainability by refactoring compiler and record-pattern tests for clarity and reliability. He addressed bugs in code completion relevance for varargs methods and refined error highlighting for forbidden references in super constructor invocations. His work demonstrated depth in compiler internals, AST parsing, and software testing, resulting in more robust and forward-compatible Java tooling.

Sep 1, 2025In September 2025, delivered a focused Java compiler fix in eclipse.jdt.core to correct forbidden reference errors in super constructor invocations and to refine error highlighting. The work computes the end offset of the constructor name accurately and narrows the error reporting range for access restrictions, resulting in more precise and actionable compiler diagnostics in the IDE. This improves developer feedback during compilation and reduces time spent diagnosing false or mislocated errors.
