This looks like the error that appears from the default library files (java)
did you by chance open the project in eclipse IDE or other IDE? 

What you can do is, clean the deployment folder from Studio Pro and then run the project.

if that doesnt work, try opening the project as “Open Existing Projects” in Eclipse IDE and see if you can build it with the exact JDK that is present in the Mendix Studio pro.
