IDebug is an advanced debugging framework for Java. It provides the standard core debugging and specification constructs such as assertions, debug levels and categories, stack traces, and specialized exceptions. Debugging functionality can be fine-tuned to a per-thread and/or a per-class basis, debugging contexts can be stored and recovered from persistent store, and several aspects of the debugging run-time are configurable at the meta-level.
OBJ3 is a program specification and proof system based on order sorted equational logic. It has been successfully used for research and teaching in software design and specification, rapid prototyping, theorem proving, user interface design, and hardware verification, among other things. It was the first language to implement parameterized programming and its module system influenced the designs of the Ada, C++, and ML module systems.
KindFTP is meant to be a complete implementation of the FTP protocol, as specified in RFC959. It provides a component that directly exposes the low-level protocol, and it supports the core protocol that is available on most Open Source FTP servers. It has untested support for ACCT, SMNT, REIN, TYPE, STRU, MODE, ALLO, and SITE command. It uses iContract to provide a full formal specification of all software, jUnit for all unit testing, and Ant as a build tool.
