for (Integer posLetter: positions){
String subText = fullText.substring(start, posLetter);
textFormat.append(subText);
subText = null; //not required
start = posLetter + 1;
}
with fullText = 5M and textFormat that's even bigger it crashes.
An friend tried with a 15M file using Lingo language and it worked without
problems and I bet .NET would have no problem either but I'll know tomorrow.

Sorry to hear that.
Would you please show some source code relative to the problem?
Well, 5000 loops of substring with a big string is terrible.
