The latest Merlin-b88 cannot run the simpliest HelloWorld test with -Xss64k
option.

This error was observed with -server -Xcomp options on Solsparc platform
for both java and java_g VMs:

% cat HelloWorld.java
class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello World");
    }
}
% ../jdk1.4.0beta-b88/solsparc/bin/java -server -Xcomp -Xss64k HelloWorld
Exception in thread "main" java.lang.StackOverflowError
% ../jdk1.4.0beta-b88/solsparc/bin/java_g -server -Xcomp -Xss64k HelloWorld
Exception in thread "main" java.lang.StackOverflowError

The test passes on all other platforms and modes:

% ../jdk1.4.0beta-b88/solsparc/bin/java -server -Xss64k HelloWorld
Hello World
% ../jdk1.4.0beta-b88/solsparc/bin/java -Xcomp -Xss64k HelloWorld
Hello World
% ../jdk1.4.0beta-b88/solx86/bin/java -server -Xcomp -Xss64k HelloWorld
Hello World

The test passes fine when more then 64k is assigned to java thread stack size:

% ../jdk1.4.0beta-b88/solsparc/bin/java -server -Xcomp -Xss65k HelloWorld
Hello World

However, the Java virtual machine cannot start if java thread stack size is less
then 64k:

% ../jdk1.4.0beta-b88/solsparc/bin/java -server -Xcomp -Xss63k HelloWorld

The stack size specified is too small, Specify at least 64k
Could not create the Java virtual machine.
