Comment 2 Mike Cvet 2007-02-27 20:52:47 UTC 
Broken on following assumptions:

Line line = stackFrame.getLines()[0];

Assuming that the StackFrame will have an array of size at least 1 - but a 
StackFrame without debuginfo returns:

if (lines == null)
  lines = new Line[0];
Comment 3 Mike Cvet 2007-02-27 21:09:52 UTC 
2007-02-27  Mike Cvet  <mcvet@redhat.com>

	* SourceBuffer.java (highlightLine): Make sure that the StackFrame has 
	available lines before grabbing them. Fixes #4106.
	* SourceWindow.java (generateProcStackTrace): Ditto.
