Inability to use custom executor

[minecrafter]

With the environment I will soon work with, I will no longer be able to create threads, and am required to use an ExecutorService. I scanned through the HikariCP source code and found that the code uses multiple executors.

Ideally the new executor setting would be in HikariConfig.

Thanks!

@brettwooldridge To share experience... I tried adding such a feature to Stormpot last year, but abandoned it because the possible failure modes of a user-supplied Executor are too numerous, and too deep in the bowels of the pool; dead-locks from bounded queues, rejected executions, delayed executions, caller-runs, etc.

@chrisvest I tend to agree. @minecrafter what kind of restricted environment is this? Surely there must be other components, web servers, etc. that are creating threads -- very few frameworks/libraries permit user-supplied ExecutorServices/ThreadPools because of the issues outlined by @chrisvest .

This no longer applies to me.

@chrisvest, thanks for explaining in more detail about the perils of allowing users to supply their own executors.

@minecrafter, I'd still be interested in hearing about this environment.
