FULL PRODUCT VERSION :
java version "1.3.1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1-b24)
Java HotSpot(TM) Client VM (build 1.3.1-b24, mixed mode)

Reproduced on Solaris 8 with both 1.3.1 and 1.4.

FULL OPERATING SYSTEM VERSION :

Linux niall.rococosoft.com 2.4.17 #4 SMP Tue Jan 29 15:28:00
GMT 2002 i686 unknown

A DESCRIPTION OF THE PROBLEM :

The error NoClassDefFoundError is usually created with the
name of the class which was not found specified as the
detail message. This makes it easy to see what class is
missing by simply printing a stacktrace.

Under a set of conditions (example code demonstrated below)
the exception is thrown without the class name - making it
very difficult to debug the root cause of the problem.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Copy the code below into test.java
2. javac test.java
3. java -cp . test

EXPECTED VERSUS ACTUAL BEHAVIOR :

Expected to see class name specified in back trace.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
Exception in thread "main" java.lang.NoClassDefFoundError
        at test.main(test.java:21)


(note - class name is missing)


This bug can be reproduced always.

---------- BEGIN SOURCE ----------
class Foo
{
    // Allows the class to compile but fail during loading
    static {
        if (System.getProperty("foo") == null)
            throw new RuntimeException("no system property foo");
    }
}


public class Test
{

    public static void main(String[] args)
            throws Throwable
    {
        try {
            Class.forName("Foo");
        } catch (Throwable t) {
            t.printStackTrace();
        }
        Foo f = new Foo();
    }
