[wildfly-dev] Proposal of an additional JBossThreadPoolExecutor (WFLY-5332)

[Panagiotis Sotiropoulos]

Hello David,

I will try to create state diagrams that show the states of the data structures in various concurrency cases.

Regards,
Panagiotis

Thanks for the effort to do this.  However it is necessary to point out 
that while you have made a very descriptive flowchart of the logic of 
the thread pool, it is unfortunately not actually a state diagram; it 
does not describe the state of the various data structures, and their 
response to external (possibly asynchronous) stimuli, which is what is 
necessary to ascertain the correctness of a concurrent algorithm such as 
the one at the core of a thread pool.
