Questions related to WorkManager short and long running threads

Issue

• will increasing max threads of short-running-threads potentially solve
  • server.log entries similar to

• Why the current thread count is always 0 for long-running-threads?
• Are short-running-threads allocated directly to the max value at jboss startup and immediately active?
• Is core threads = max threads valid?
