Created attachment 148013 [details] netbeans-ide-profile I know that this has happened before - all other bug reports say it's fixed, but this is still happening for me: I already had Cygwin installed, so I added the gcc, make etc. packages and added my cygwin/bin folder to my path. So these tools are perfectly available and runnable through my command line (both the windows one and the cygwin terminal). I tried it with Netbeans 8.0 first, but couldn't create a project because the IDE was apparently still trying to figure out my build tools. I then uninstalled 8.0 and installed the nightly build which appears to have the same problem. The versions of my build tools: GCC 4.8.3 g++ 4.8.3 make 4.0 gdb 7.6.50.20130728-cvs My java version is 1.8.0_05 I can see that it's doing something since the memory usage is going up steadily until the GC kicks in. Maybe that's just the default behavior though. I don't know if that helps you, but I profiled the IDE for a couple of seconds (from lowest memory usage until the GC run). You can find it attached to this post. Hope this helps!
Same here. I use MinGW and Cmake. Sometimes Netbeans gets stuck at "Validating Tool collection on localhost". I have to kill Netbeans with Task Manager and restart it.
