File that contains long line at the end.

The GWT generate html files that contains a lot of JavaScript. Some of these files are big (10 000 line) and contains a few lines that are long. Scrolling down such file in editor consume 100% of CPU for few seconds. 

For example the attached file contains at the end a line that has more than 35 000 characters. When this line is not painted, then the scrolling is ok, when the line is in the view area, the AWT freeze for 10 seconds on my machine. I also attaching a snapshot, where you can see that the problem is in painting.
