Subject [jira] Commented: (HTTPCORE-58) IllegalStateException after cancelling
Date Sat, 31 Mar 2007 11:18:25 GMT

    [ https://issues.apache.org/jira/browse/HTTPCORE-58?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12485715
] 

Oleg Kalnichevski commented on HTTPCORE-58:
-------------------------------------------

Anders,

To me this looks like a reasonable behavior. If the connection gets shutdown while it is still
being initialized, throwing an IllegalStateException seems appropriate to me. The only alternative
to that is synchronizing on the connection instance, which it personally would like to avoid
for performance reasons. If that's the price you are willing to pay you may want to extend
the DefaultNHttpClientConnection and make all its methods synchronized.

What do you think?

Oleg
