Description Jiri Kovalsky 2015-01-15 10:57:00 UTC 
Product Version: NetBeans IDE Dev (Build 201501150001)
Java: 1.8.0_25; Java HotSpot(TM) 64-Bit Server VM 25.25-b02
Runtime: Java(TM) SE Runtime Environment 1.8.0_25-b17
System: Linux version 3.13.0-24-generic running on amd64; UTF-8; en_US (nb)

Description:
============
User cannot compare two self profiling snapshots (*.npss) generated by the NetBeans IDE, because "Select Snapshot to Compare" dialog only accepts "*.nps" files.

Steps to reproduce:
===================
1. Launch NetBeans IDE and click "Profile the IDE" toolbar button or press Alt+Shift+Y.
2. After a while press the same button or press the same keystroke to stop the profiling.
3. In Editor toolbar press top left "Export IDE snapshot..." button, browse to some directory and click "Export" button.
4. Click last "Computes the difference between two comparable snapshots" button above table with threads.
5. In "Select Snapshot to Compare" dialog click "Browse..." button and notice that "Open Snapshot" file chooser only displays *.nps files.
