JavaSound Minim Errors

Hi All,

I'm recording some sound in a Processing sketch.  It seems to be working fine but I get the errors below.  Any idea what is going on?  My sketch is working but I don't like seeing these errors.  I'm running Fedora 17 Linux and Processing from processing-2.0b7-linux64.tgz
