Description:
Client Connections in MySQL Workbench gives unhandled exception.

How to repeat:
I run MySQL Workbench. In Administration tab, I click on Client Connections - Refresh. I get an Unhandled exception.

Log file shows:

Ok thanks for the reply. Perhaps it is a duplicate. Will it be fixed? We just want to see the client connections in mysql workbench.
