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.
