Jed Wesley-Smith updated FELIX-2332: ------------------------------------ Attachment: ExtensionManager.java.patch attached is a simple patch that reduces the scope of the sync block to the iteration. > Lots of contention on ExtensionManager.openConnection(URL) > ---------------------------------------------------------- > > Key: FELIX-2332 > URL: https://issues.apache.org/jira/browse/FELIX-2332 > Project: Felix > Issue Type: Bug > Components: Framework > Reporter: Jed Wesley-Smith > Attachments: ExtensionManager.java.patch > > > This method is synchronized, apparently to protect is the iteration through > the m_extensions list. We have seen significant blocking in our applications > as this lock encompasses the call to URL.openConnection as well. > As this list is rarely changed, a copy-on-write structure would be more > appropriate, but at the very least the, only holding the lock during the > iteration would be far preferable. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
