This does not make sense, it appears impossible for the line to throw an NPE. Is it reproducible? What files are you diffing? Is one of them a binary file?
There is also a 3rd-party plugin that seems to have problems with NetBeans 8.1: .netbeans/8.1/modules/org-netbeans-modules-regexplugin.jar. Try to get rid of it, start NB with fresh userdir, do not import anything and let me know if you're still getting the error.

have you seen this again?
