Thread dump taken via console during a hang event.

I am still able to reproduce this as of the 201604040001 nightly build.

Was able to duplicate the hang with SvnKit disabled.

Another thread dump

Tried again from a simple Maven Java SE project that was not checked into source control, and was able to capture this thread dump upon experiencing the hang.  Looks like all it takes to trigger the hang is for the user to mash Ctrl+C multiple times.
Comment 5 teamridco_nickd 2016-04-11 22:59:19 UTC 
Attempted to duplicate issue on another machine with a similar configuration (Windows 10 ENT + NB 8.1 + JDK 1.8u77), and was not able to.  Suspect a plugin issue; will post further troubleshooting results.
Comment 6 teamridco_nickd 2016-04-12 04:07:23 UTC 
Identified as an issue with the Open File At Cursor plugin.

Duplication Steps:
1. Install the Open File At Cursor plugin under NB 8.1 (any build between 8.1 main and the current nightly as of 2016-04-11).
2. Open any Java source file.
3. Select some text.
4. Rapidly and repeatedly hit Ctrl+C
5. Attempt to switch editor tabs, close the IDE, or use the IDE's taskbar button's right-click context menu to exit the IDE.

Expected result: The IDE switches to the new tab or closes when the close button/menu option is clicked.

Actual result: The IDE hangs with about 15% CPU usage.

Closing issue as it is a third-party problem.
