 The reason for the additional call pcd match is that prior to compliance level 1.4, 
 Java compilers produced bytecodes that call A.doIt() (the defining type of the method),
 rather than B.doIt() (the declared type in the program text). The generated call to
 A.doIt() is not matched by the call pcd used in the before advice.  At 
 compliance level 1.4, the bytecodes retain the declared type of the receiver in the
 program source, generating a call to B.doIt(), which <i>is</i> matched by the call pcd.

 <p>This is a good example of why the recommended style is to use <code>call(* doIt(..)) && target(B)</code>,
 which always matches based on the actual type of the receiver.
