Subject [jira] Commented: (HTTPCORE-206) NPE in DefaultClientIOEventDispatch
Date Wed, 23 Sep 2009 14:36:16 GMT

    [ https://issues.apache.org/jira/browse/HTTPCORE-206?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12758719#action_12758719
] 

Asankha C. Perera commented on HTTPCORE-206:
--------------------------------------------

I've tried both with Synapse 1.2 original JARs and a private maintenance branch, and I cannot
re-create this exception. Could you attach the very fist log file where this error will be
reported after the startup? If the log file contains sensitive information, you may zip it
and send it to me directly
