The change to the active choices plugin at commit 372d91b is causing problems and we cannot use the latest versions of the plugin without reverting this commit and building on our own.

The problem is strange. But, is appears to be mostly a performance issue. With this change, we are seeing '504 gateway error' failures because of connection timeouts. It is somehow related to the artifactory plugin, because the jenkins log file contains multiple occurrences per second of the following log message.

(omitting message as it's not related to the performance issue)
