Build: NetBeans IDE Dev (Build 201706120001)
VM: Java HotSpot(TM) 64-Bit Server VM, 25.111-b14, Java(TM) SE Runtime Environment, 1.8.0_111-b14
OS: Mac OS X

User Comments:
GUEST: Working on a project.

GUEST: Started NetBeans, took several minutes and ~80$% of my CPU time to background scan the large project I have loaded for work (as usual, please make it so I can turn background scanning on and off), when it was done, I had this error.

rweaver: Just starting up IDE

GUEST: Extremely high load, veeeery slow UI. No background task visible. Working on a small (1200 lines) Javascript file ... can't call it "working" really.
Netbeans tends to unusable a lot lately. Only one project open. No new plugins or extensions added lately. Process-list shows Netbeans-Java Process at over 500% CPU ...
