Problem with MessageListener

Hi,

04-14 13:40:13.418:

I/dalvikvm(8378): Failed resolving Lde/xxx/mobileclient/services/XMPPHelper; interface 3155 'Lorg/jivesoftware/smack/MessageListener;'

I am getting this error with newer asmack snapshots. Reverting back to the one from 20.3 works fine but i havent testet each one individualy.

Thanks

Fuu
