# JTrac 3: an issue tracker rebuilt after REA analysis of JTrac 2.3.3

> JTrac 3 is an independent issue tracker informed by the author's REA MCP study of the JTrac 2.3.3 WAR. Inspection of its bytecode and application files informed a feature catalogue and persistence model; the new implementation uses Java 25, Spring Boot 4, React 19 and PostgreSQL 18 for workflows, custom fields and issue management.
