I have this java application that uses JOGL and it worked great last week, without changing anything in the code i am suddenly getting all of these exceptions and the visual portion of the application isn't working whatsoever.  I'm just curious if anyone has experienced a similar problem within the past week or so and discovered a solution to the problem because I have no idea where to even begin to look.
