Description Selpi 2015-03-20 14:11:17 UTC 
Product Version = NetBeans IDE 8.0.2 (Build 201411181905)
Operating System = Linux version 3.16.0-32-generic running on amd64
Java; VM; Vendor = 1.8.0_40
Runtime = Java HotSpot(TM) 64-Bit Server VM 25.40-b25

I just tried to use NB as an editor for a quick changes in MySQL database and got an absolutely unresponsive UI.

Steps to reproduce (I tried it 4 times and every time got locked):

open connection to a database, select something (in my case  'select * from node;')

I needed to change multiple values in the end of a table, so jumped to an end of 10000+ records, and a couple of pages back from the end (-40 records).

Select cell with value using mouse, F2 to edit, change value, switch to next cell, F2 etc. Commit changes. 

It's kinda random, but after 5-10 values changed and commited to database when I start to edit just another cell the UI stops responding to any key pressed. Mouse still able to select menues/buttons etc.

I got no exceptions or errors, it just stops working and I have to restart NB to fix it.

Can't reproduce it in Win7 with the same NB 8.0.2. So looks like this bug is linux specific or depends on some settings/plugins.

My current setup is Ubuntu 14.10 with gnome shell 3.12.2.

Thank you for your report! But I don't quite understand what you are getting:

You say:

"I just tried to use NB as an editor for a quick changes in MySQL database and got an absolutely unresponsive UI."

and:

"Mouse still able to select menues/buttons etc."

So did the GUI _react_ to mouse clicks (opening menus)? If not, could you please try to grab a thread dump when the situation happens?

1. Open a terminal
2. run: jps
   to get a list of PIDs for all running java processes 
   (netbeans is the one listed as "Main")
3. run: jstack <PID> > /tmp/thead_dump.txt

please attach the resulting file "thread_dump.txt" here. Thank you!
