Issue Summary
When we add a while space in the Class/Package name field and save the Logging and Profiling, it gives the System error.
This is reproducible on Data Center: Yes
Steps to Reproduce
Step-1. Go to 
> General Configuration > Logging and Profiling.
Step-2. If you run Confluence in a cluster, select a cluster node.
Step-3. Enter the name in the Class/Package name field, with an extra space at the beginning / end or in-between.
For example " com.atlassian.confluence.mail.session" or "com.atlassian.confluence.mail.session " or "com.atlassian.confluence.mail. session"
Step-4. Select Add entry to add the new class or package to the list.
Expected Results
It should not break the Logging and Profiling screen.
Actual Results
It breaks the Logging and Profiling screen and show System Error.
Workaround
As any modification on the logging page will always be reset after a Confluence restart, workaround is to restart Confluence. This will reset the logging back to default and resolve the issue.
Note
In the logs, we could see we get a java.lang.IllegalArgumentException.
