java takes too much CPU time

[Heikki Suopanki]

Java application takes 10-20% of CPU time even with lot of 'sleep()'.
On Solaris it takes less than 0.1%.
Is that normal?

Even a minimal application which only sleeps and sleeps and
prints a message to stdout takes 1-2% of CPU time. 

Redhat 5.1, jdk1.1.6
Machine is a dual 233Mhz.
