WildFly 17.0 Model Reference

  1. WildFly 17.0
  2. subsystem=ejb3
  3. thread-pool

A thread pool executor with an unbounded queue. Such a thread pool has a core size and a queue with no upper bound. When a task is submitted, if the number of running threads is less than the core size, a new thread is created. Otherwise, the task is placed in queue. If too many tasks are allowed to be submitted to this type of executor, an out of memory condition may occur.
