This answer is derivative to Alfaville's answer, but if you happen to have set a field named pageSize in your LazyDataTable descendant it may cause the same problem. This was the case with me and I didn't see the problem until I saw the Override of setRowIndex.

You must override the method setRowIndex

Example: 

@Override
public void setRowIndex( int rowIndex ) {

   if ( rowIndex == -1 || getPageSize() == 0 ) {
    super.setRowIndex( -1 );
   } else
    super.setRowIndex( rowIndex % getPageSize() );
}

Its seems like a know issue

datatable: java.lang.ArithmeticException: / by zero

Issue 1544: LazyDataTable.setRowIndex throws arithmetic exception: division by 0.

It has a FIX/WORKAROUND (so claimed by some user)
