Error verifying method org/kxml2/io/KXmlParser <init>()V

Hi,

I am trying to use kXml, but I always get a runtime error if my code
reach the instantiation of KXmlParser.

Error text:
Error verifying method org/kxml2/io/KXmlParser <init>()V 
Approximate bytecode offset 65: Inconsistent or missing stackmap at target 
ALERT: Error verifying class org/kxml2/io/KXmlParser

I am using JBuilder 7 with MobilSet 3.01 and WTK 1.04

thanks forward
Zsolt
