Class ShutdownRejectedExecutionHandler

java.lang.Object

org.jgroups.util.ShutdownRejectedExecutionHandler

All Implemented Interfaces:

RejectedExecutionHandler

public class ShutdownRejectedExecutionHandler
extends Object
implements RejectedExecutionHandler

ShutdownRejectedExecutionHandler is a decorator RejectedExecutionHandler used in all JGroups ThreadPoolExecutor(s). Default RejectedExecutionHandler raises RuntimeException when a task is submitted to ThreadPoolExecutor that has been shutdown. ShutdownRejectedExecutionHandler instead logs only a warning message.

A ThreadPoolExecutor.DiscardPolicy drops a rejected task silently, ie. without raising a RejectedExecutionException. As callers such as ThreadPool.execute(Runnable) would otherwise treat a discarded task as accepted, a RejectedExecutionException is raised on the policy's behalf.
