The section "12.3.3 Resolution of Symbolic References" of The Java Language
Specification contains the following:

"This error may be thrown at any point in the program that uses a symbolic reference to the type, directly or indirectly:

    IllegalAccessError: A symbolic reference has been encountered that 
    specifies a use or assignment of a field, or invocation of a method,
    or creation of an instance of a class, to which the code containing the 
    reference does not have access because the field or method was declared 
    private, protected, or default access (not public), or because the class
    was not declared public. This can occur, for example, if a field that is
    originally declared public is changed to be private after another class
    that refers to the field has been compiled (��13.4.6)." 

Verifier permits to use the private field from another class.
