What WOULD you do?

Eye for an eye. Or better yet two eyes. Escalate boldly and actively till the bully backs off and maybe a bit more to make sure he's not faking.

Whoa, lots of tough guys here! I didn't know Java programming turns regular Joes into superwarriors.

I started with PHP... 4.3... 20 years ago. And that was just the beginning. Java is for peacenicks.

Alas, I still don't have a single tank to my name, so it's not me that will be doing the shooting. Or even deciding to shoot.

At 45 years I already lived too long and seen too much. I don't mind universe giving me its best shot at mythical thermonuclear war. I fully expect it to be pathetic.
