        Description: 1.4.2 javac NPE in Check$Validator.visitSelect

         FULL PRODUCT VERSION :
        ./java -version
        java version "1.4.2_14"
        Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_14-b03) Java
        HotSpot(TM) Client VM (build 1.4.2_14-b03, mixed mode)


        ADDITIONAL OS VERSION INFORMATION :
        SunOS 5.8 Generic_108528-14 sun4u sparc SUNW,Ultra-4

        A DESCRIPTION OF THE PROBLEM :
          Verified this NPE happens when following conditions are met.

        - The class in the java source being compiled (A) implements an interface
        (B)
          whose super class (interface) is not visible during compilation.
        - .class exists for the interface (B) above.
        - (A) implements another interface that is in a package.

        This problem happens on JDK 1.4.2_* on Solaris and Windows.

        myc.java (A)
        myitf/myitf.java // interface which (B) extends
        myitf/myitf.class //
        myitf2.class (B) .class
        myitf2.java (B)
