JUnit Popup can freeze app

On a project that has not been compiled, when you ask
to run JUnit tests, it pops up a dialog saying:

Must Compile All Source Files to Run Unit Tests:
To unit test all documents, you must first compile all
out of sync source files. Would you like to compile
all files and run the specified test?

If you click on the "x" to close the popup, the
RuntimeException "Invalid returnCode from
showConfirmDialog: -1" is thrown which freezes the app.

I'm going to go ahead and say that closing the dialog
defaults to the user pressing no unless anyone has any
objections or thoughts. I'll also see if I can find
any other places this might occur.
