The wildfly-threads artifact encapsulates the old threads subsystem and is also still used as a library to help support management resources in other subsystems that provide executors and thread factories.

This artifact still produces instances of various long-deprecated Executor implementations from JBoss Threads. We should update such code to use EnhancedQueueExecutor instead, except for org.jboss.as.threads.ScheduledThreadPoolService, which should use
JBossScheduledThreadPoolExecutor.
