Andrew Mashenkov commented on IGNITE-3812:
------------------------------------------
{noformat}
final IgniteConfiguration cfg = new IgniteConfiguration();
cfg.setLocalHost("127.0.0.1");
cfg.setManagementThreadPoolSize(-1);
Ignition.start(cfg);
{noformat}
The code above results in IllegalArgumentException:
{noformat}
java.lang.IllegalArgumentException

> Project: Ignite
> Issue Type: Task
> Affects Versions: 1.6
> Reporter: Andrew Mashenkov
>
> An IllegalArgumentException will be thrown from one of java standard
> implementation of ThreadPool without any information about wrong parameter
> if incorrect value provided (e.g. if set threadPoolSize <= 0). So, it is not
> obvious which executor service initialization has failed.
> See IgnitionEx.IgniteNamedInstance class.
