Description

From time to time I have a problem that Netbeans were not responding when I tried to open find dialog(via Ctrl+F). I.e It is possible to switch a window via mouse click but I have to wait around 10 seconds. This laziness can be reverted  when I close the window in which I tried to open a find dialog. In a error log I can see this exception:

java.lang.NullPointerException
SEVERE [null]: Last record repeated more than 10 times, further logs of this record are ignored until the log record changes.
SEVERE [null]: Last record repeated 7547 times in total.
SEVERE [global]
