Hello! I am using Hudson on an ARM machine using openjdk. Surprisingly
everything works quite well. However if I try to use the --daemon option, then I
get a traceback:

I just picked the javanet subcomponent since I had to pick one and it seemed the
most appropriate. Googling for "UnsatisfiedLinkError jnidispatch" generates some
potentially useful reports within other projects.
