Funny story...
Got a small college assignment based on Java and Cassandra(database). The database shell was running fine. Spent 5 days removing the random java exceptions and working on the basic connectivity, searched everywhere on Stack overflow and other forums for solutions and still no help.
So, I decided to write a program that would print only the output as I knew what would be the output when it will run. Took a screenshot of it and made up a cover story to tell my professor that I did it on a friend's computer.
But while I was taking a screenshot of the Eclipse with code window and output window, some random syntax errors popped up.(but they weren't syntax error).
So I created a new project and copied the pom.xml file and the code into the new one(I tried this one before and it didn't work). And there were no errors. So I took a screenshot of it with output of different file and opened a different file.

But then, don't know what came across my mind and I clicked on run just to see if this works, and it worked fine. And now I'm like.. WTF JUST HAPPENED!!
