Answer 1

I was having the same problem with Netbeans 8.1, Windows 10. It was also hanging when I tried to compile and refactor. It would sometimes say 100% done yet continue background scanning for hours. I closed the project in which this was happening, and switched to a simple project and the problem went away. So I examined my code. I had class A extending class B, then class B importing class A. When I changed this, the endless looping in Ant stopped.
