Description Joanne Lau 2008-03-26 23:38:20 UTC

Build: 080325

Attempt to enter a long text

- DnD a class element
- Add a comment element to the class
  and begin to enter text (about 45 chars) 
- Click <Return>

 This causes the entire IDE to freeze.

 Please see attached thread dump and outOfMemoryError.

Comment 4 Thuy.d Nguyen 2008-04-01 19:19:50 UTC

The breakUpLines method missed handling the situation where the width of a single word is longer than the widget's
width. The loop condition was not properly set which made the loop being executed indefinitely and the array of lines
growing until out of memory.

Fixed.
