Additional Information

From  https://knowledge.broadcom.com/external/article?articleId=195808
In version 6.8 the old Automation Studio method of upgrading agents has been ported to the ROC and this problem has been fixed there. The fix involves specifically removing symbolic links before it attempts to delete folders. The upgrade process itself, in the 6.8 ROC, firsts prompts whether you want to use the new upgrade procedure. If you deselect this option then it will use the previous/ASAP method where this fix has been implemented to improve how the upgrade process handles the removal/upgrade of the JRE.
