Java HotSpot(TM) Server VM (build 2.0fcs-E, mixed mode)

There appears to be a limit on the number (or total size of) strings that
can be interned. This is independent of the heap size.

  To reproduce this, run the following code:

import java.util.*;

public class TestIntern {

    public static void main(String argv[]) {

        ArrayList l = new ArrayList();
                      
        for (int i=1; i<(1<<30); i++) {
            String s = ""+Math.random();
            if (i%10000==0) { System.out.println(i+" strings"); }
            l.add(s.intern());
        }

    }
}

On both Windows NT and Solaris, this crashes after 430000 strings with
a non-catchable exception:

   Exception in thread "main"

There is no stack trace produced. The thread just dies. The problem
appears to be associated with HotSpot and does not occur on Classic VM.
