17 | * A slightly tweaked default thread factory that uses the following pattern: | |
18 | * <code>[%s].config.change.%d.thread.%d</code>, where %s stands for application name, | |
19 | * the next number will tell one how many redeployments this app had during this container's | |
20 | * lifetime and the last digit, thread count, should always be 1. Left there for debugging | |
21 | * purposes to quickly locate any duplicate threads trying to perform a redeploy. | |
