java.util.concurrent.ExecutionException when selecting a connection in the Web Intelligence Client

Hello,

Our users are currently getting an error when trying to open a connection in the Web Intelligence Rich Client. If they click the connection a few times it eventually goes away, and they can edit it. Based on the error I'm not really sure where to begin troubleshooting. I tried checking with our CMC administrator account, but I get a different error because that account doesn't have access to BW.

Here is a screenshot of what the user is doing:

Here is the detailed error message:
