Strange behavior of javac

I don't mean to use -d for -cp.

Please note that I'm not using an installed JDK, but a newly built jdk  
(with class files in /classes instead of rt.jar), so $JM/classes  
should be already at the top of bootclasspath.

   $ javap x.A
   Compiled from "A.java"
   public class x.A extends java.lang.Object {
       public x.A();
   }

   $ javac -d $JM/classes B.java
   B.java:1: cannot find symbol
   symbol: class A
   package x; public class B extends A {}
                                   ^
   1 error

May this is a class loader issue?
