Build: NetBeans IDE 8.0 (Build 201403101706) VM: Java HotSpot(TM) Client VM, 24.45-b08, Java(TM) SE Runtime Environment, 1.7.0_45-b18 OS: Windows XP User Comments: genkabuki: Used Clearcase to undo a checkout that was open in a tab in the NetBeans IDE. At that point NetBeans became very slow (was already consuming 590MB+ of RAM) and had a 13% CPU utilization. I then clicked on "Restart IDE" from the File Menu plugin.
