Known Issue: Error Message When Submitting Assignments

Did you know that Blackboard has a limit to the number of characters that can be in a file name? If you see an error message of "java.lang.NullPointerException" when submitting an assignment, that means there are too many characters in the file name (must be less than 126 characters, including spaces).

The fix is to simply rename (or re-save) the file with fewer characters and re-submit. Students, that might mean asking the instructor for another attempt at submitting your homework assignment.
