[jira] [Commented] (FELIX-4645) Service already unregistered
exception from HttpServicePlugin
[ https://issues.apache.org/jira/browse/FELIX-4645?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14138877#comment-14138877 ]
Bram de Kruijff commented on FELIX-4645:
----------------------------------------
I think it is a race conditions that happens servlets deregister in concurrence with the HttpService asynchronously shutting down. That is something likely to happen in your scenario and I also saw this trace frequently in integration tests where bundles are stopped/started all the time. Upgrading to 2.3.0 solved it for me.
