LDIFF is an enhanced language-independent line differencing tool built upon the Unix diff and overcomes its limitations in determining whether an artifact line has been changed or is the result of additions and removals

[This project is frozen, but has an offspring with more features: https://github.com/jeffhain/jadecy ] JCycles provides treatments to compute cycles, or just strongly connected components, in directed graphs in general, or in classes or packages dependencies graphs parsed from class files (major version <= 51, else does best effort). It uses Tarjan's algorithm for SCCs, and Johnson's for cycles, with continuations instead of recursion, which allows to handle large graphs (< Integer.MAX_VALUE vertices). Requires Java 5 or later.

PSF is a path-sensitive, inter-procedural program analysis framework developed on top of Soot.
