FULL PRODUCT VERSION :
java version "1.4.2-beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-beta-b19)
Java HotSpot(TM) Client VM (build 1.4.2-beta-b19, mixed mode)

FULL OS VERSION :
Microsoft Windows XP [Version 5.1.2600]

EXTRA RELEVANT SYSTEM CONFIGURATION :
* environment with or without JAVA_HOME=c:\java.
* I have the JDK installed in c:\java.
* My PATH picks up javap from c:\java\bin.

A DESCRIPTION OF THE PROBLEM :
Two problems

1. The plain command

  javap java.lang.Object

(no explicit -classpath option) no longer works in 1.4.2-beta. It used to work in all versions upto and including 1.4.1_02.

I have to specify a classpath of $JAVA_HOME/jre/lib/rt.jar for it to work.

2. Even if I do specify this classpath explicitly, it no longer prints out the flag bits or the inner classes.

For instance,

  javap java.util.Map

used to print out flags like "ACC_SUPER not set", and also the contents of the nested interface Map.Entry. In 1.4.2-beta, it no longer prints these out.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Run 'javap java.util.Map' from the command line

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Javap output:

Compiled from Map.java
public interface java.util.Map
    /* ACC_SUPER bit NOT set */
{
    public abstract int size();
    public abstract boolean isEmpty();
    public abstract boolean containsKey(java.lang.Object);
    public abstract boolean containsValue(java.lang.Object);
    public abstract java.lang.Object get(java.lang.Object);
    public abstract java.lang.Object put(java.lang.Object, java.lang.Object);
    public abstract java.lang.Object remove(java.lang.Object);
    public abstract void putAll(java.util.Map);
    public abstract void clear();
    public abstract java.util.Set keySet();
    public abstract java.util.Collection values();
    public abstract java.util.Set entrySet();
    public abstract boolean equals(java.lang.Object);
    public abstract int hashCode();
    public static interface java.util.Map. Entry
    /* ACC_SUPER bit NOT set */
{
        public abstract java.lang.Object getKey();
        public abstract java.lang.Object getValue();
        public abstract java.lang.Object setValue(java.lang.Object);
        public abstract boolean equals(java.lang.Object);
        public abstract int hashCode();
    }
}
ACTUAL -
1. Without the -classpath option:

   ERROR:could not find java.util.Map.

2. With the -classpath option:

Compiled from "Map.java"
interface java.util.Map{
    public abstract int hashCode();
    public abstract int size();
    public abstract void clear();
    public abstract boolean isEmpty();
    public abstract boolean containsKey(java.lang.Object);
    public abstract boolean containsValue(java.lang.Object);
    public abstract boolean equals(java.lang.Object);
    public abstract java.util.Collection values();
    public abstract void putAll(java.util.Map);
    public abstract java.util.Set entrySet();
    public abstract java.util.Set keySet();
    public abstract java.lang.Object get(java.lang.Object);
    public abstract java.lang.Object remove(java.lang.Object);
    public abstract java.lang.Object put(java.lang.Object,java.lang.Object);
}

Notice:
(a) inner class not printed.
(b) flags not printed
(c) formatting slightly screwed up ({ on the same line as the classname, and
no spacing before the {).

ERROR MESSAGES/STACK TRACES THAT OCCUR :
ERROR:could not find java.util.Map.

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
Specify -classpath $JAVA_HOME/jre/lib/rt.jar to at least get the top-level class.

No workaround for displaying the nested class.

Release Regression From : 1.4.1_03
The above release value was the last known release where this
bug was known to work. Since then there has been a regression.
