The "-extdirs" does not work - actually arguments to extdirs are effectively
ignored and flag causes standard extensions not to be searched.

To reproduce:

% cd /tmp
% mkdir q
% cd q
% cat > Frog.java
public class Frog {
        public int rat;
}
% javac Frog.java
% jar cf toad.jar Frog.class
% rm Frog.class
% cd
% javap -extdirs /tmp/q Frog
Class 'Frog' not found

           --- fix the bug here ---

% javap -extdirs /tmp/q Frog
Compiled from Frog.java
public class Frog extends java.lang.Object {
    public int rat;
    public Frog();
}
