weird memory and cpu usage running jdk14 on -current

[Jiawei Ye]

I am running a fairly recent -current(Jul21). Just recompiled jdk1.4
and tried to run snipsnap (snipsnap.org). Using top, I see the
following numbers:

last pid: 34048;  load averages:  0.49,  0.25,  0.50    up 0+04:21:12  17:58:23
53 processes:  1 running, 52 sleeping
CPU states:  0.0% user,  0.0% nice,  0.8% system,  0.8% interrupt, 98.4% idle
Mem: 134M Active, 15M Inact, 63M Wired, 11M Cache, 34M Buf, 20M Free
Swap: 512M Total, 54M Used, 458M Free, 10% Inuse

  PID USERNAME PRI NICE   SIZE    RES STATE    TIME   WCPU    CPU COMMAND
34048 leafy     20    0  1644M   114M kserel   0:26 235.72% 231.20% java

1644M is "a lot", but I doubt if it's actually using that much. And
the CPU time is just not right.

Could anybody shed some light on this?
