-* [Checker Framework](http://types.cs.washington.edu/checker-framework/) - Enhances Java’s type system to make it more powerful and useful.
 * [Checkstyle](https://github.com/checkstyle/checkstyle) - Static analysis of coding conventions and standards.
 * [Error Prone](https://github.com/google/error-prone) - Catches common programming mistakes as compile-time errors.
 * [FindBugs](http://findbugs.sourceforge.net/) - Static analysis of bytecode to find potential bugs.

-* [Daikon](http://plse.cs.washington.edu/daikon/) - Daikon is an implementation of dynamic detection of likely invariants; that is, the Daikon invariant detector reports likely program invariants. Can generate JML specs based on the invariants.
+* [CATG](https://github.com/ksen007/janala2) - A concolic unit testing engine for Java programs. Automatically generates unit tests for Java programs using formal methods.
+* [Checker Framework](http://types.cs.washington.edu/checker-framework/) - Pluggable type systems for Java. Includes nullness types, physical units, immutability types and more.
+* [Daikon](http://plse.cs.washington.edu/daikon/) - Daikon detects likely program invariants and can generate JML specs based on those invariats.
 * [Java Modeling Language (JML)](http://www.jmlspecs.org) - A behavioral interface specification language that can be used to specify the behavior of Java modules. It combines the design by contract approach of Eiffel and the model-based specification approach of the Larch family of interface specification languages, with some elements of the refinement calculus. Used by several other Java verification tools.
-* [Java Path Finder (JPF)](http://babelfish.arc.nasa.gov/trac/jpf) ([repository](http://babelfish.arc.nasa.gov/hg/jpf/jpf-core/)) - "The Swiss army knife of Java verification." A model checker for Java (bytecode) and more. By NASA
-* [jCUTE](https://github.com/osl/jcute) - The Java Concolic Unit Testing Engine (jCUTE) automatically generates unit tests for Java programs. Concolic execution combines randomized concrete execution with symbolic execution and automatic constraint solving. See also [CATG](https://github.com/ksen007/janala2).
-* [JMLOK 2.0](http://massoni.computacao.ufcg.edu.br/home/jmlok) - Setects nonconformances between Java code and JML specification through the feedback-directed random tests generation, and suggests a likely cause for each nonconformance detected
+* [Java Path Finder (JPF)](http://babelfish.arc.nasa.gov/trac/jpf) - A JVM formal verification tool containing a model checker for Java bytecode and more. Created by NASA.

 * [KeY](http://key-project.org/) - The KeY System is a formal software development tool that aims to integrate design, implementation, formal specification, and formal verification of object-oriented software as seamlessly as possible. Uses JML for specification and symbolic execution for verification.
-* [OpenJML](http://jmlspecs.sourceforge.net/) ([alternate website](http://openjml.github.io/))- Formal methods tool for Java and the Java Modeling Language (JML). OpenJML translates JML specifications into SMT-LIB format and passes the proof problems implied by the Java+JML program to backend SMT solvers.
