java hashtable

I'm getting unexpected results from hashtable-get/put! under the -jvm
target.  However, when using bigloo3.6a, the results look correct to me.

Makefile:
--------

PROG=bgtest
BGLFLAGS=-g -jvm -jvm-cinit-module -jvm-purify
OBJS= bigloo/test.class \
	${PROG}.class
BGLJAR=/usr/local/lib/bigloo/current/bigloo_u.zip 
all: .afile ${OBJS}
	java -classpath .:$(BGLJAR) $(PROG)

%.class: %.java
	javac -classpath .:$(BGLJAR) $<

bigloo/test.class: bigloo/test.scm
	bigloo ${BGLFLAGS} -c -o $@ $^

.afile: bigloo/test.scm
	bglafile $^ > $@

clean:
	rm -f $(OBJS) .afile

(The file /usr/local/lib/bigloo/current is a symbolic link.  I point this to
the bigloo version, then do a 'sudo make install' from the appropriate
source directory.)

bgtest.java:
-----------

import bigloo.test;

public class bgtest{
    public static void main(String args[]){
	test.add(3);
	test.add(3);
    }
}

bigloo/test.scm:
---------------

(module bigloo.test
	(java
	 (export add "add"))
	(export
	 (add ::int))
	)

(define *hash* (make-hashtable 20000))

(define (add count)
  (let ((keys (iota count)))
    (for-each
     (lambda (key)
       (let ((fnd (hashtable-get *hash* key)))
	 (hashtable-put! *hash* key "value")
	 (printf "key: ~s fnd: ~s\n" key fnd)))
     keys)))

Under bigloo 4.0b, output is 
make -k 
bglafile bigloo/test.scm > .afile
bigloo -g -jvm -jvm-cinit-module -jvm-purify -c -o bigloo/test.class

Is there something wrong with my code?  If not, what has changed in
bigloo?
