 OK. It seems to be related to java/3096 and java/3965:
 
   http://gcc.gnu.org/ml/java-prs/2001-q2/msg00070.html
 
 So I rewrote the only loop that uses a pre-incremented array access
 and the test started to work:
 
   RC5 Java Demo (gregh@lightspeed.net)
   Keys: 256 keys
   Time: 1 ms
   Rate: 256000 keys/sec
   Keys: 512 keys
   Time: 4 ms
   Rate: 128000 keys/sec
   Keys: 768 keys
   Time: 6 ms
   Rate: 128000 keys/sec
 
 java/3096 and java/3965 are next on my list of things to do. I'll keep
 you posted.
