Why do I receive a Java exception when I open the Profiler on Mac?

Whenever I open the Profiler or make it the current window, I receive the following Java exception in the MATLAB Command Window. This happens in both MATLAB R2016b and R2017a on my Mac.

This error is likely being caused by a third-party accessibility tool on Mac, such as Moom or BetterSnapTool.
 
To see if a tool is enabled, follow these steps:
1. From the Apple menu, select System Preferences.
2. Open Security & Privacy.
3. Click the Privacy tab.
4. Select Accessibility in the list on the left.
 
If there are any tools enabled here, try unchecking them to resolve this incompatibility.
