[jira] Commented: (HTTPCORE-205) AbstractMultiworkerIOReactor needs optional Latch to signal when ready.

    [ https://issues.apache.org/jira/browse/HTTPCORE-205?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12751623#action_12751623 ] 

Oleg Kalnichevski commented on HTTPCORE-205:
--------------------------------------------

Patrick,

Actually why do care when the worker threads are started at all? What is important that the I/O reactor is ready to accept incoming connections. Why do not you simply use ListenerEndpoint#waitFor() method to wait for a listener to become ready? This, I believe, should eliminate the need for a countdown latch.

For details see

> AbstractMultiworkerIOReactor may take some time getting ready ( needs to start threads for example ). In order to ensure that it is ready before starting to send requests, a CountDownLatch is needed.
> This is important for our test suites which are launch the reactor and then immediately trying to hit it. ( and failing )
