StackOverflow caused my unsaved files to be lost, so I've marked with P2. 

I'was going to find type, which was supposed to be in clipboard, but in the mean time I've copied there thread dump of tomcat process. So I pressed Ctrl+V and then Enter and that was all I could do. "go to type" window is modal, buttons did not work. I was forced to kill netbeans. 

My mistake, but unsaved changes were lost. 

Steps to reproduce:

1. Open IDE with some project 
2. Press Ctrl+O to open "Go to Type" dialog
3. Paste thread dump from VisualVM (large one) (example below)
4. IDE starts to search for type, and freezes (sometimes it is possible to press Cancel, sometimes not)


Limiting input field length should fix the problem (I hope).


I've observed stack trace in IDE log:
