I'm running the NetBeans IDE 8.0 on Java: 1.8.0_20-ea. Just saw a giant
over-sized checkbox in a popup menu (see attached). Could it be related to
the retina patch mentioned in the thread below?

I don't see oversized checkmarks in the main menus. The oversized
checkmark is still present in the popup menu after I restart the IDE.

It does not depend on an external monitor, as I don't one and have observed this, too (screenshot of a menu attached).
I've seen this in a menu, that is not in the system menu bar, but in the app window itself.
This happened when running an ancient version of HPJmeter. Just double-clicked on the jar, and I was able to observe the issue.
