I've tried going back to 5.2.1 and have the same problem, so the issue is probably with something else I installed, not a change from 5.2.1 to 5.2.2.  The most likely culprits are an Apple system update combined with an extension, or Python, which I installed to get something else to work.  I'm not sure if Scilab uses Python or something that gets stepped on by the installation, but it is one of the things that changed.

The message about the Java version also shows up in the console on that machine, but since it works there I don't think that's the issue.  The other messages seem to be referring to JackOSX, which is a configurable audio router.  I don't know why Scilab would be trying to start or connect to that.  It's not set up as the default audio device and Scilab was working with the same version of that installed before.  I can only guess that an Apple OS update or the Python install have created an extension conflict with an extension that wasn't a problem before.  The machine where Scilab is working has the same system version but I did not install Python or JackOSX.  Does anyone have any suggestions as to what I could try to debug this further?  I'd rather not have to start ripping out extensions or cleaning out the Python install, which there doesn't seem to be an easy way to do.

We don't have this issue on our testing Mac OS X machines and I confirm
that we are not doing anything with the sound card on the start up of
the software.
However, we noticed some random behaviors under Mac. Please let me know
if you find a workaround on this issue.
