Blackdown JDK 1.3.1 and User Mode Linux

Hello,

I tried to run Jetty (http://jetty.mortbay.org) under the 
Blackdown JDK 1.3.1 in a User Mode Linux VM.

It works fine (i.e. it does what it is supposed to) but: Java 
consumes around 25% CPU on the real hardware. When I run Jetty 
under the Blackdown JDK 1.3.1 on the real hardware it doesn't 
consume any CPU when idle.

I wrote a Hello World style Program that listens on a port (see 
attachment) and ran it in the UML VM and on the real hardware.
On the real hardware it doesn't consume any CPU (as expected). 
But when I run it in teh User Mode Linux VM, it consumes about 
20% CPU.

Does anybody have an idea whether it is the Java VM that 
misbehaves or whether it is the User Mode Linux Kernel?

Thanks in advance.
Yours, Thomas
