#8 JavaGrader crashes if do not pick a file
To repeat problem:
1) Start JavaGrader with no parameters
2) When the file chooser comes up, pick Cancel instead of a valid config file
The program will crash. Instead, it should exit more gracefully and provide an error message to the console about the problem.
In version 53 updated javagrader.class at lines 84-88 added an if statement to make the program exit gracefully when the cancel option is selected in the file chooser dialog.
