[jira] [Updated] (WW-3580) Critical performance issue in production environment as thread dumps are leading to OGNL 3.0 thread blocking! Website could be backed out!

     [ https://issues.apache.org/jira/browse/WW-3580?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Philip Luppens updated WW-3580:
-------------------------------

    Attachment: Small_bugfix_on_the_performance_patch_provided_in_WW-3580_.patch

I spotted the bug in the performance patch that solves the problem with the failing tests. It was a simple matter of not setting the return value after a Field was found.

This web application is rolled into production; however, due to serious performance considerations the website is in danger of being rolled back.
