Contemplate, an Edinburgh University spin-out company, has developed an 
advanced static analysis tool, ThreadSafe, that may be of interest to 
readers of concurrency-interest.  ThreadSafe specifically targets Java 
concurrency defects and includes some dedicated treatment for 
java.util.concurrent.  It handles enterprise-scale Java codebases and 
includes tight integration with Eclipse.

ThreadSafe is in an early stage - currently we are on version 1.1 - but 
it is already in use finding serious concurrency defects in projects at 
a couple of large investment banks.  You can get an impression of what 
it does from the very simple example in

We are looking for a limited number of participants for a trial, to give 
us feedback on what is in ThreadSafe now and on our plans for near-term 
new features.  Please get in touch with me directly if you are 
interested in taking part.

Of course, I am also very happy to demonstrate ThreadSafe to potential 
paying customers!  If you are in this category, please get in touch!

Here are answers to some obvious questions:

1. Can ThreadSafe find bugs in my tricky lock-free algorithm?

Probably not. We look for the sort of concurrency mistakes that 
application developers make in large code bases.

2. What kind of trial participants are you looking for?

We are mainly looking for two kinds of people:

a. Java concurrency gurus who might be interested in how ThreadSafe 
could be used by software developers that they teach/advise.

b. Application developers in industry who make substantial use of 

We need to be able to identify who you are and your affiliation.

3. Is this free software?

ThreadSafe is a commercial product and there is currently no free 
version.  At some point we may introduce a free or low-cost version. 
The trial is free, but we expect feedback.
