Default Thread Pool Size
Since Payara Server 220.127.116.11
The thread pool
thread-pool-1 starts with a minimum size of 2
instead of 1 (like in previous versions)
This includes the benefit of allowing users to execute tasks
concurrently using the
ManagedScheduledExecutorService components included with Java EE
Concurrency Utilities (JSR-236).
Without this change, new tasks submitted to these service components
would just have been queued in a linear fashion.
This minor optimization is configured on the default domain template (so all newly created domains inherit it).
