Can't save edits to sudoers policy in MCU, there isn't any highlighted text
说明
In MCU after making changes to the sudoers policy the save button is not active. Also the even though the highlighting checkbox is checked there isn't any highlighting.
原因
This was being caused because in Java RE 1.7 Oracle has changed the default security settings.
解决办法
Setting security to meduim and accepting all the warnings resolved the issue.
