I upgraded my local jackrabbit source after a while (2 months), and rebuilt it.
Whenever I wan't to start my application (that uses jackrabbit) I get the folowing error:

java.lang.NoSuchMethodError: org.apache.jackrabbit.core.virtual.VirtualNodeState.<init>(Lorg/apache/jackrabbit/core/virtual/VirtualItemStateProvider;Ljava/lang/String;Ljava/lang/String;Lorg/apache/jackrabbit/name/QName;[Lorg/apache/jackrabbit/name/QName;)V

And this is the same even if I use an empty repository.

Please help! :)

Thank you
