Product Version: NetBeans IDE Dev (Build 201104020400)
Java: 1.6.0_24; Java HotSpot(TM) 64-Bit Server VM 19.1-b02
System: Linux version 18.104.22.168-1.2-desktop running on amd64; UTF-8; en_US (nb)
Projects Properties->Profile->Show profiling indicators during run = ON.
But indicators don't appear.
I cannot reproduce this issue.
Could you, please, try the newer version of NB?
