Serviio on headless Linux

Hi,

I'm trying to run Serviio on a headless Linux server box. For some reason, even though the serviio startup script explicitly sets java.awt.headless=true, it tries to access the java.awt.AppContext and java.awt.SunToolkit all the time, which fails miserably:

  Code:

Exception in thread "LibraryAdditionsCheckerThread" java.lang.NoClassDefFoundError: Could not initialize class sun.awt.SunToolkit

As a result, it's impossible to do pretty much anything with the server.

The interesting thing is that with the same JRE on the same machine, test code executing the same calls runs just fine (e.g. new GregorianCalendar() or even SharedSecrets.getJavaAWTAccess(), which just returns null).

This is on an Arch Linux, running jre7-openjdk 7.u40_2.4.2-1

Edit: The offending AppContext gets initialized by this call:

It's the image resize functionality. the -D parameter should get around this, so I'm not sure. Serviio normally runs on headless servers (like NASes), maybe try the Oracle Java instead of OpenJdk, if you can.
