Hi Markus,

I have the same problem with JDK 1.3.0_02 when I try to run Orion from the
ports:

   bash-2.04# java -version
   java version "1.3.0_02"
   Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0_02)
   Java HotSpot(TM) Client VM (build 1.3.0_02, interpreted mode)
   bash-2.04# java -jar orion.jar
   Auto-unpacking /usr/home/ernst/hello-planet/build/hello-planet.ear... done.
   Auto-unpacking /usr/home/ernst/hello-planet/build/hello-planet/hello-planet-web.war... done.
   Auto-deploying hello-planet (New server version detected)...
   Auto-deploying hello-planet-ejb.jar (No previous deployment found)... #

I noticed some weird things:

   * There seem to be a lot of processes. This may have to do with the fact
     that every thread is mapped to a process.

   * It takes a long time for all processes to die, there are 45 seconds
     between the death of the first java process and the last.

   * The processes run at a very low nice-level. This makes the system very
     irresponsive.
