Obfuscation error

Question

Hi,
When i set obfuscation level off or high, i build successfully.
But when i set obfuscation level from 1 to 8, i build fail.
I want to set obfuscation level about 5-6 for an j2me midlet.
Netbeans 6.5 show error information when obfuscation fail:
Unexpected error while computing stack sizes:
Class = [org/netbeans/microedition/lcdui/TableItem]
Method = [paint(Ljavax/microedition/lcdui/Graphics;II)V]
Exception = [java.lang.IllegalArgumentException] (Stack size becomes negative after instruction [126] ificmpge +6 (target=132) in [org/netbeans/microedition/lcdui/TableItem.paint(Ljavax/microedition/lcdui/Graphics;II)V])
Error: Stack size becomes negative after instruction [126] ificmpge +6 (target=132) in [org/netbeans/microedition/lcdui/TableItem.paint(Ljavax/microedition/lcdui/Graphics;II)V]
Plz let me why and how to solve this trouble.
Thanks and regards.
