[Building Sakai] Abstrct Method error

[mohan at samudrasoftware.com]

Hi,

 I am working on sakai2.6.2. I have face a problem at adding a new field
to account. I have change all the java classes and database also. And
modified in sakai-kernal-1.0.13 classes and interfaces also. Finally I
got a problem "BUILT FAILURE".

And I find some errors at in surefire reports. i.e. "abstract method error".

The exception is :

<error type="java.lang.AbstractMethodError"

message="org.sakaiproject.user.impl.DbUserService$$EnhancerByCGLIB$$b689ae97.addUser(Ljava/lang/S
