[Validate] Thread-safe implementations #418
Description
Context
In #412 , we described an issue regarding how a TESTAR multi-thread implementation combined with the implementation of a synchronized method was provoking the web driver module to hang when starting a new sequence.
The #415 contained a solution that removed the synchronized updateHandlesList implementation with a multi-thread safe CopyOnWriteArrayList solution.
TESTAR developers and OU students tested this solution. However, this multi-thread implementation in TESTAR requires further investigation and validation. Also, identifying and validating other TESTAR features that use this approach.
