FULL PRODUCT VERSION :
java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-b92)
Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)

  Bug also seen in:

java version "1.3.1_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1_01)
Java HotSpot(TM) Client VM (build 1.3.1_01, mixed mode)

FULL OPERATING SYSTEM VERSION :

Microsoft Windows 2000 [Version 5.00.2195]

ADDITIONAL OPERATING SYSTEMS :

Cygwin B20

A DESCRIPTION OF THE PROBLEM :
An infinite loop of method calls causes termination
of client VM without java.lang.StackOverflowError stack
trace being shown, or only with a part of the stack trace
shown. This makes it very hard to debug.
The same behavior is found for hotspot VM in 1.3.1.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Use the following Test.java

2. Compile with /j2sdk1.4.0/bin/javac Test.java

3. Run with /j2sdk1.4.0/bin/java -client -classpath c:Test

4. You see a series of printouts:
Test.main()
count = 1
count = 2
count = 3
...
count = 4570
count = 4571
count = 4572

5. The VM terminates with no error thrown.







EXPECTED VERSUS ACTUAL BEHAVIOR :
You should see first a series of printout messages
and then a java.lang.StackOverflowError thrown followed
by VM termination.

Instead you see the series of printouts which
goes to "count = 4572". The VM terminates without
any error reported. This happens in 1.4 with
client VM and in 1.3.1 with hotspot VM.

If you comment out the print command
    System.out.println("count = " + (++count));
and repeat the process, you will see a truncated
stack trace of java.lang.StackOverflowError.
(This is similar to reported bug 4222717).

It seems like the client VM (or hotspot VM in 1.3.1)
does not leave enough memory to print the stack trace
of the StackOverflowError.

The behavior where the VM terminates without any error
makes it very hard to debug.










This bug can be reproduced always.

---------- BEGIN SOURCE ----------
public class Test {


    private static int count = 0;


    public static void doThis() {
        System.out.println("count = " + (++count));
        Test.doThis();
    }


    public static void main(String[] args) {
System.out.println("Test.main()");
        Test.doThis();
    }
}

---------- END SOURCE ----------

CUSTOMER WORKAROUND :
The system behaves correctly in 1.3.1. and 1.3.0.with the
classic VM. You first see a list of printouts and
then a *complete* stack trace of
java.lang.StackOverflowError.

Also in 1.3.0. you get the following message before
termination with hotspot VM:

#
# An EXCEPTION_STACK_OVERFLOW exception has been detected
in native code outside the VM.
# Program counter=0x77f822a0
