Error description
There are performance issues, specifically high CPU usage, that occur with certain REST APIs such as TaskSocialResource, which uses the newInstance method on the javax.xml.datatype.DatatypeFactory class. The following REST APIs are noted to have performance issues: v1/process/<instance-id>?action=update v1/task/<task-id>?action=update v1/performance/query v1/social/instance/<instance-id>/stream v1/social/task/<task-id>/stream
