Presentation Transcript

  1. RAC Support for JML onEclipse Platform Amritam Sarcar (Advisor: Yoonsik Cheon) Support by NSF under grant CNS-0707874

  2. Introduction • Java Modeling Language (JML) • Formal behavioral interface specification language for Java • Documentation of Java modules (classes and interfaces) • Spectrum of tool support • From runtime assertion checking (RAC) to theorem proving • RAC and ESC/Java most widely used

  3. Problems with JML tools • Lack of robustness • Lack of extensibility • Not designed for it, e.g., code base for developing other tools • Maintenance overheads • Built upon a not-well-supported open-source Java compiler • No support for Java 1.5 features such as generics • Future changes in Java

  4. Project Goal and Approach • Goal: To redevelop the JML compiler (jmlc) • Java 1.5 features such as generics • Future Java language changes, e.g., Java 1.8 and beyond • Code base for other JML tools • Approach • Develop a new compiler based on the Eclipse Java compiler • Design it with extensibility in mind

  5. Accomplishments • Investigated several alternative architectures • Tool architectures: double-Round, incremental, bytecode weaving, and AspectJ-based • Bytecode architecture: inline, wrapper, and semi-wrapper • Proposed “incremental architecture” through analysis, comparison, and feasibility study (e.g., prototype)

  6. Incremental Architecture

  7. Current and Future Work • Baseline architectural code for the incremental architecture • Full-blown development in collaboration with other JML developers at Kansas State and Concordia
