Thread Modelling

In my university days I came across a Java app in one of my courses. You basically modeled your threads (any actions they perform etc.) in a simple language. It would draw a diagram and identify and issues with your threading. Does anyone know what this app is called? I have tried for the last 30 mins on Google but can't find anything.

• I guess you mean "Thread State Diagrams". Maybe something like this?

  Jonathan C Dickinson : That's exactly the concept; but there was an application to create (and 'debug' those).

  Lucero : hmmm... maybe jBixbe ? http://www.jbixbe.com/
