Introduction

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


Problems with jml tools

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


Project goal and approach

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


Accomplishments

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)


Incremental architecture

Incremental Architecture


Current and future work

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
