Subject [jira] [Updated] (HTTPASYNC-3) I/O reactor has been shut down (Example code is attached)
Date Sat, 23 Apr 2011 09:16:05 GMT

     [ https://issues.apache.org/jira/browse/HTTPASYNC-3?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Oleg Kalnichevski updated HTTPASYNC-3:
--------------------------------------

         Priority: Major  (was: Critical)
    Fix Version/s:     (was: 4.0-alpha2)

I cannot reproduce the problem. Code does not compile because HttpCallback class is not defined.
