I have a fairly simple "hello world" style project with two profiling points. One to reset results, a second a few lines later to "Take Snapshot". Neither appears to get "hit" and the second one doesn't produce results. I've tried it in different modes, a.o. "Methods" and "Objects". I'm running NetBeans 8.2, using Maven, on JDK 1.8.0_66, in 64 bit mode.
I've found the problem and it's me. Profiling points are only hit in case of "instrumented runs" and I was doing "sampled runs". The confusion was probably caused because the new profiling GUI initially guides you to the "configure profiling" drop-down menu at the top-left of the window. Once you've done that and made your choices, e.g. "methods", a second menu button appears at the top-right in the menu bar of the same window. That's what you need to click to get an additional drop down labeled "profile:" that in turn offers the choice between "sampled" and "instrumented".
