This issue also seems to also cause problems with Application Links in JIRA. The Symptom is that JIRA appears to be slow to update information in the Development Panel ('Dev Panel') with wait times up to 30 minutes for information to be up to date.

Workaround

Root cause investigation is ongoing but the possible culprit is an improperly starting plugin. This issue has been known to resolve itself with an application restart but if you do encounter this error please provide an application Support Zip to Support at https://support.atlassian.com so that we can investigate further.

ClassNotFoundException: scala.collection.JavaConverters
