ThreadSafe is a source code analysis tool that identifies application risks and security vulnerabilities associated with concurrency in Java code bases, using whole-program interprocedural analysis. ThreadSafe is used to identify and avoid software failures in concurrent applications running in complex environments. (Wikipedia).

MountainWest RubyConf 2013 Immutable Ruby by Michael Fairley
Most Ruby code makes heavy use of mutable state, which often contributes to long term maintenance problems. Mutability can lead to code that's difficult to understand, libraries and applications that aren't thread-safe, and tests that are slow and brittle. Immutability, on the other hand,
