Hotspot Client VM (build 1.3-internal-release, mixed mode),
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0beta-b01), throws
NullPointerException instead of StackOverflowError or OutOfMemoryError while infinite
recursive method invocation. See test source and diagnostics below.

You need compile the test.java file with oldjavac, because javac crashes
while compiling the test.

The bug can be reproduced in
/net/sqesvr/vsn/GammaBase/Bugs/<this bug number>
directory, using doit.sh script.

-------------------------- test.java ---------------------------------
public class test {

  public static int counter = 1;

  static int Runner() {
        counter = counter * -1;
        int i = counter;
        if(counter < 2) counter += Runner();
        return i;
  }

  public static void main(String argv[]) {
        try{
                Runner();
        } catch (StackOverflowError e) {
                System.out.println("OK! StackOverflowError was thrown");
        } catch (OutOfMemoryError e) {
                System.out.println("OK! OutOfMemoryError was thrown");
        } catch (NullPointerException e) {
                System.out.println("Error! NullPointerException was thrown");
        }
  }
}
